I. Composition and Space 1. Frame orientation: 9:16. The figure’s height occupies about 60%–70% of the frame. Leave at least 30% of the frame height above the head to the top edge, with clearly visible empty wall space on both left and right sides. 2. Visual focus: Keep the background minimal to emphasize facial features and eye contact. II. Lighting and Shadow Style 1. Key light type: Strong natural daylight, slightly side backlit, cool-toned, creating a high-contrast light–shadow relationship. 2. Light and shadow characteristics: A large amount of hard light filtered through leaves creates dappled spots covering the wall and the subject. Edges are extremely sharp, penumbra is very narrow, with strong contrast between light and dark. 3. Highlight control: Large areas of the bright background are overexposed while still retaining a small amount of texture, creating a glowing spatial effect. III. Subject Replication 1. Facial features: Delicate and cute face shape, Japanese-style bangs, long black hair reaching the waist, relatively large eyes, slender and elongated nose bridge. 2. Makeup: Light pink lip color, clean makeup with a Korean-style tendency. 3. Clothing: A short, pure white bandeau-style top exposing the waist, form-fitting but not tight. IV. Color System 1. Primary color tendency: Cool white and neutral gray as the base, with deep black as the main visual anchor. 2. Accent color strategy: Almost no high-saturation accents; visual tension is created through light–dark contrast and material differences. 3. Color temperature relationship: Overall fresh and restrained. V. Camera and Imaging Texture 1. Camera angle height: Below eye level with a slight upward angle. The camera is positioned farther back for a wider framing, retaining the full arms and the blade, with the action not touching the frame edges. 2. Depth of field: The background remains entirely in focus. 3. Sharpness style: Realism-oriented, with moderate detail sharpness. 4. Motion rendering: A strong sense of frozen posture, with no obvious motion blur at the frame edges. 5. Prop reflections: Bright highlights and clear reflections on metal surfaces, enhancing a cold, sharp character. VI. Atmosphere and Narrative Quality 1. Emotional tone: Calm, detached, with a slight sense of danger and ritual. 2. Sense of time: A fleeting moment under strong afternoon sunlight, like a fragment cut by light. 3. Style positioning: A combination of realistic portraiture and theatrical posing, inserting sharp tension into an everyday setting. 4. Viewing experience: A bright background presses inward, surrounding the scene, while the subject is sculpted between shadow and highlight. 5. Light–dark curve: Increase overall contrast and lift the highlights. VII. Action and Pose Replication 1. Arm posture: Both arms raised and crossed. Hands and the knife handle are positioned above the head. The palms lightly grip the handle, with slender fingers extended outward. 2. Prop posture: A long blade angled diagonally, extending from near the head downward to the right, without exceeding the top edge of the frame. 3. Head angle: Head slightly tilted upward, chin gently tucked, gaze directed straight at the camera, expression cool and restrained. 4. Pelvis orientation: Pelvis and hips fully turned sideways to the camera, shown in a true profile, rotated ninety degrees. 5. Waistline presentation: Clear side profile of the waist, with the abdomen and lower back forming a lateral silhouette, no frontal view of the waist or abdomen. 6. Shoulder and neck lines: Shoulders slightly raised, collarbone area catching the light, neck elongated. 7. Bodily tension: A frozen pose with a ritualistic quality that combines defense and attack; the overall posture is stable yet impactful.

Using the uploaded subject as the reference, create an ultra-photorealistic black-and-white graphite pencil portrait. Strictly adhere to her facial proportions, bone structure, jawline, eye shape and spacing, nasal structure, lip shape and fullness, original hairstyle, hairline, and natural parting. Composition and Pose Framing: 3:4 vertical portrait, waist-up composition, including down to the shirt’s waist tie area. Layout: The subject is positioned slightly off-center, leaving open space in the direction of her gaze (to the right). The head is placed roughly in the upper third of the frame. The pose should feel elegant and balanced, using the folds of the shirt and the arm lines to guide visual focus toward the face. Posture: The torso leans slightly to the left, shoulders relaxed and natural, head gently turned to the right. Expression: Soft gaze directed off-frame to the right, with a gentle, distant, and contemplative expression. Hands: The right hand is raised gracefully, wrist slightly bent, index fingertip lightly touching the lower lip, thumb resting beneath the chin, other fingers naturally curled inward. Hand structure must be anatomically accurate, with clearly defined joints and natural nails, conveying a relaxed, introspective feeling. Detail Rendering Face: Use refined graphite shading to emphasize smooth cheekbones, a delicately sculpted nose, and a well-defined jawline. Lips should appear full, with subtle blending along the lip centerline to enhance dimensionality. Eyes must be highly detailed, including delicate eyelid shadows, clear long eyelashes, and naturally full arched eyebrows. Skin should be rendered through seamless blending and smooth tonal gradients. Hair: Dark hair rendered with fine, controlled ხაზwork. Styled in a slightly loose low bun or tied back at the nape, suggesting soft volume. Include loose strands at the temples, forehead, and around the ears, with a single fine strand falling along the left cheek. Use layered strokes to create realistic hair texture and depth. Clothing: An elegant wrap-style V-neck blouse with a soft silk or satin drape. Include the overlapping deep V neckline, waist tie, naturally radiating folds from the knot, and the smooth tension across the torso fabric. Sleeves are slightly loose, with gathered fabric around the forearms and natural deep folds at the inner elbows due to the pose. Cuffs are cleanly structured, featuring a single round button and a vertical slit. The material should convey soft sheen and natural tension lines of the wrapped structure. Background and Lighting Background: Textured sketch paper with extremely subtle diagonal cross-hatching, softly faded edges to enhance depth. Lighting: Soft, diffused studio lighting with smooth tonal transitions, realistically shaping facial volume. Light gently illuminates the face, casting subtle shadows beneath the chin, fingers, and shirt folds. Overall Style Museum-quality classical realism with a romantic and melancholic tone. Technique requires extremely precise linework, controlled hatching, and subtle visibility of paper texture. The image should be rendered in monochrome graphite, with the lower portion of the portrait softly fading into the paper, creating an unfinished artistic effect. Final output should be in 8K ultra-high resolution, 3:4 vertical format.

[Core Concept] Based on the uploaded subject and outfit reference, generate an ultra-photorealistic outdoor hot spring portrait. The theme is “Goddess in the Spring,” capturing a serene moment of the subject immersed in a crystal-clear turquoise hot spring, creating a dreamy, warm, and intimate healing atmosphere. Strictly preserve the subject’s facial features, structure, and body proportions, and accurately reproduce all outfit details. [Subject and Pose] The subject stands in waist-deep hot spring water, body angled in a 3/4 orientation toward the camera, forming a subtle S-curve through the torso. Both arms extend outward to the sides, fingertips lightly touching the water surface, creating gentle ripples. The head tilts upward approximately 15 degrees, looking directly at the camera with a calm, soft expression and slightly parted lips. Long hair (matching the uploaded subject’s color and style) flows behind the shoulders, with the ends floating on the water surface. A large olive-green flower (peony or lotus) is placed behind the left ear. The gaze is warm and inviting, shoulders relaxed and slightly drawn back. [Wardrobe Styling] Strictly follow the uploaded outfit reference: a deep olive-green one-piece swimsuit with all-over letter prints. Details include: halter neckline, crisscross lace-up detail at the chest, side cut-outs at the waist, and a repeating tonal letter pattern across the fabric. The color is deep olive green with matching tonal typography. [Composition and Depth of Field] Use a 4:5 vertical frame with a medium-close composition (waist-up). The camera is positioned slightly above the hot spring edge, angled downward at 20–30 degrees. The image is structured in three layers: * Foreground: shimmering water surface with caustic light patterns projected onto the skin and swimsuit. * Midground: sharply focused subject. * Background: lush green trees with hints of golden autumn leaves, along with wooden resort structures. The water naturally surrounds the lower body, forming a framing effect. Use a 50mm lens at f/2.0 to achieve shallow depth of field and subject emphasis. [Lighting and Color] Lighting is natural golden-hour backlighting, coming from above and behind the subject at a 45-degree angle on the right. Effects include: 1. A golden rim light outlining hair and shoulders. 2. Steam particles creating visible volumetric light rays (Tyndall effect). 3. Sparkling highlights on the water surface. 4. Sunlight refracting through moving water, casting realistic caustic patterns onto skin and fabric. Color grading follows Fujifilm “Nostalgic Negative” style: warm, nostalgic tones with soft glowing highlights, rich but natural greens, and warm, accurate skin tones. Avoid high contrast; maintain a soft, dreamy tonal range. [Environment and Atmosphere] The setting is a luxurious outdoor hot spring surrounded by dense tropical vegetation. Multi-level wooden resort structures are visible in the background. Steam and mist rise from the water surface, catching the golden backlight to create a soft, ethereal glow. The water is exceptionally clear with a turquoise hue, revealing rocks beneath and allowing accurate caustic light patterns to be visible. [Technical Constraints] Achieve ultra-photorealistic quality. Avoid any form of skin smoothing, plastic-like textures, murky water, overcast gray lighting, indoor pool appearance, oversaturated HDR effects, or illustrative/anime styles. Ensure physically accurate lighting behavior, realistic steam diffusion, and correct underwater caustic projection.
