Photorealistic night smartphone portrait. A completely fictional adult Japanese woman in her 20s, not resembling any real person, celebrity, model, or influencer.
Vertical 9:16. Taken outdoors at night or at a dim night spot, like a natural snapshot for social media. Slightly close-up composition centered on the upper body: the woman angles her body slightly to the side while turning her face toward the camera and looking straight into the lens. Neck and shoulder lines are naturally relaxed, with a friendly soft smile. Both hands are raised to chest-side/face level, fingertips touching to form a large heart shape. Hands and fingers follow slender natural adult-female proportions, with accurate finger overlaps and joints.
Hair is long dark-brown to black-brown, reaching below the chest. Natural near-center part; roots not too fluffy; very gentle waves toward the tips. Keep fine individual hair strands, wispy face-framing hairs, and slight messiness — not CG-uniform hair. Soft brown highlights appear on the lit side; the other side sinks naturally into deep burnt-brown to black.
Face is a small egg shape, soft not-sharp contours. Naturally large dark-brown eyes, thin delicate eyeliner, natural double eyelids, faint under-eye bags (tear troughs). Brows are natural brown, not too thin. Small delicate nose, nose bridge not over-emphasized. Lips are natural pink-beige with a subtle sheer gloss. Makeup is a clean natural pink-brown style, not overdone — like a real snapshot of a young adult woman.
Outfit: minimalist matte-black strappy bikini — a small triangle halter top with thin neck straps and straight underbust strings, and matching ultra-high-cut bikini bottoms with tiny thin triangular front and thin high-rise side straps; long strings wrap around the waist and cross into a prominent X at the lower belly; sparse geometric thin-strap silhouette. No prints, bows, rings, buckles, or ornaments. Render seams and even the fiber texture of the straps realistically.
Lighting is the top priority. The surroundings are quite dark; the background is near-black night scenery. A small smartphone flash or weak direct light near the camera illuminates her face, arms, shoulders, and hands from a front-ish angle. Not an overpowering white flash — a slightly warm, soft direct light. Small smooth highlights on cheekbones, nose bridge, forehead, lips, shoulders, and forearms; the off-light side falls smoothly into shadow.
From the left-rear or diagonal-rear, a very weak warm ambient / orange rim light thinly outlines the outer edge of the hair and a few strands. The background carries only a few very weak red/orange/green bokeh lights or floor reflections to hint at a night event or outdoor lounge, but background details stay too dark to discern.
Skin is not over-airbrushed. Bright translucent complexion but not porcelain: very fine pores, fine texture, faint redness, and natural color variation on cheeks, around the nose, forehead, and arms. Slight dewy sheen where the flash hits; small specular highlights on cheeks, nose tip, and shoulders — not oily. The skin has a soft translucency and blood tone, as if light returns from within. Arms and backs of hands share the same texture as the face, not flat and uniform.
Color tone is warm-leaning neutral. Skin holds a slight pink-to-peach cast, strengthening contrast against the black background. Saturation not too high; highlights creamy; shadows retain a hint of brown/red to avoid crushing to black. About smartphone-HDR level, avoiding HDR's unnatural edge enhancement.
Camera is smartphone-equivalent 24-28mm wide-angle, close to the subject. Face and hands are sharply resolved; background blurs naturally. Keep slight handheld feel, fine sensor noise, and the smooth graininess typical of low-light shooting. Avoid over-sharpening, AI-style ultra-fine detail, or studio perfection — it should feel like a photo accidentally well-taken on a phone at night.
Composition frames from the top of the head to the chest, with hair flowing largely to the left edge. Face sits slightly left of center, the heart shape toward the upper right, so both face and hands carry the frame. A slight body tilt avoids a stiff straight-on portrait, keeping a natural, intimate social-media mood.
