Reiwa Gyaru Casual Bikini Smartphone Snap

{
  "title": "Reiwa Gyaru Casual Bikini Smartphone Snap",
  "identity_lock": "None. Do not resemble any real person, celebrity, influencer, or identifiable individual.",
  "overall_direction": "Vertical 4:5 ultra-realistic private smartphone photo of a 22-year-old adult Japanese woman at a real-world summer resort poolside or beachside setting. The image should feel like a friend casually took the photo on an iPhone during an ordinary summer outing, not like a professional model shoot. Prioritize the impression of an unexpectedly flattering candid smartphone photo that could naturally appear on Instagram or TikTok. Avoid the polished perfection of advertising, gravure, commercial fashion photography, or AI-generated glamour imagery.",
  "style": {
    "photography": "Authentic handheld iPhone 16 Pro main-camera photography, casual Instagram-style lifestyle snapshot, photorealistic and observational rather than cinematic.",
    "image_processing": "Natural smartphone Smart HDR with slight shadow lifting, moderate contrast, natural to slightly restrained saturation, realistic automatic white balance, slightly enhanced local clarity without aggressive sharpening, subtle JPEG compression, fine sensor noise, and mild noise remaining in darker areas.",
    "highlights": "Allow small areas of natural highlight clipping on bright sky, reflective water, pale pavement, or sunlit surfaces. Do not recover every highlight perfectly.",
    "motion": "Extremely subtle motion blur may appear on a few loose hair strands, fingertips, bikini ties, or other small moving details.",
    "color_grading": "No cinematic color grading, no heavy filter, no teal-orange palette, no artificial film look."
  },
  "subject": {
    "age": "22-year-old adult woman",
    "ethnicity": "Japanese",
    "character": "Beautiful contemporary Reiwa-era gyaru with a polished soft-gyaru aesthetic. She should look like a fashionable young woman naturally seen on Instagram or TikTok in the 2020s. Trendy and feminine but approachable, not an exaggerated Heisei gyaru, not heavily tanned, not an anime-like gyaru stereotype.",
    "face": "Small softly oval face with realistic individual proportions, dark brown almond-shaped eyes, subtle natural under-eye fullness, softly defined nose, glossy pink-beige lips, and slight natural left-right facial asymmetry. Attractive but not geometrically perfect or doll-like.",
    "hair": "Long milk-tea brown to warm dark-brown dyed hair with soft see-through bangs and layered face-framing strands. Preserve several flyaway hairs, slightly uneven strands, and a few naturally displaced ends instead of perfectly arranged salon hair.",
    "makeup": "Modern Japanese and Korean-influenced soft-gyaru makeup: softly defined parallel brows, thin slightly extended eyeliner, separated curled lashes, subtle aegyo-sal definition, natural rosy-beige cheek color, glossy pink-beige lips, lightweight luminous base makeup. Makeup should remain visibly real rather than digitally airbrushed.",
    "skin": "Healthy fair-to-light natural skin tone with realistic pores, tiny variations around the nose and cheeks, mild uneven coloration, subtle natural sheen from skincare, makeup, heat, or sunlight, and visible fine skin texture on the face, neck, shoulders, arms, and torso. Beauty correction is minimal."
  },
  "body": {
    "build": "Naturally feminine hourglass figure with a defined waist and realistic soft curves.",
    "anatomy": "Physically plausible adult anatomy and believable body proportions. Preserve subtle asymmetry, natural skin compression, realistic posture, and normal soft-tissue behavior rather than an exaggerated AI-generated silhouette.",
    "presentation": "Healthy, contemporary and naturally feminine rather than bodybuilder-like, doll-like, or artificially sculpted."
  },
  "outfit": {
    "main": "Contemporary minimalist bikini suitable for a modern Japanese resort or beach trip.",
    "design": "Simple trendy triangle or bandeau-inspired bikini with thin straps and a clean 2020s silhouette, in a muted black, ivory, pale blue, or dusty pastel tone.",
    "fit": "The fabric follows the body naturally with realistic tension, minor wrinkles, tiny strap-position differences, and slight asymmetry caused by movement.",
    "accessories": "Minimal SNS-friendly accessories such as small silver earrings, a delicate necklace, a thin bracelet, simple rings, or sunglasses. Avoid excessive luxury styling or elaborate fashion-editorial accessories."
  },
  "scene_environment": {
    "location": "A believable outdoor hotel poolside, seaside resort terrace, or casual beachside area during summer.",
    "background": "Real swimming pool or ocean water, deck surface or sand, sun loungers, parasols, railings, vegetation, hotel architecture, towels, bags, or other ordinary environmental details where appropriate.",
    "realism": "Background should remain relatively legible because this is not portrait mode. Include small real-world imperfections such as faint water marks, slightly displaced furniture, minor surface wear, footprints, wrinkles in towels, reflections on glass, or subtle signs of normal use.",
    "avoid": "Do not create an immaculate luxury-advertisement environment or unrealistically empty cinematic resort."
  },
  "pose_expression": {
    "pose": "Natural relaxed standing or casually shifting pose as if she momentarily stopped while talking with the friend holding the phone. Weight rests slightly more on one leg, shoulders and hips are not perfectly level, arms and hands fall naturally rather than forming a professional modeling pose.",
    "expression": "Soft natural expression with a faint relaxed smile or neutral friendly look, as though she has only just noticed the camera.",
    "gaze": "Natural gaze toward or slightly beside the smartphone lens rather than intense fashion-model eye contact.",
    "imperfection": "Allow an intermediate micro-moment rather than a perfectly frozen pose: a strand of hair moving, fingertips adjusting something, shoulders subtly uneven, or expression captured between reactions."
  },
  "camera": {
    "device": "iPhone 16 Pro main wide camera aesthetic",
    "composition": "Vertical 4:5 composition.",
    "perspective": "Mostly eye-level, photographed by a friend from normal conversational distance.",
    "lens_behavior": "Natural smartphone wide-camera perspective approximately equivalent to a standard phone main camera. Preserve very mild edge stretching and optical distortion rather than perfectly correcting the frame.",
    "framing": "Slightly imperfect handheld framing. Place the subject modestly off-center, keep unequal negative space, and allow the frame to tilt naturally by a few degrees.",
    "focus": "Ordinary smartphone autofocus with the subject clearly readable but without artificial edge separation.",
    "depth_of_field": "Relatively deep smartphone depth of field. Background remains recognizable and moderately sharp. No artificial portrait-mode blur or creamy full-frame-camera bokeh.",
    "capture_feel": "A friend casually raising the phone and taking one or two quick photos rather than deliberately constructing a composition."
  },
  "lighting": {
    "source": "Primarily real natural daylight appropriate to the location.",
    "behavior": "Smartphone HDR gently balances face and surroundings without eliminating natural shadows.",
    "shadows": "Preserve weak but believable shadows beneath the chin, hair, arms, bikini edges, and along the side of the body.",
    "highlights": "Natural sunlight creates small uneven highlights on skin and hair. Slight clipping on extremely bright background areas is acceptable.",
    "avoid": "No studio softbox, beauty dish, artificial rim light, cinematic three-point lighting, or impossibly even illumination."
  },
  "micro_realism": {
    "skin": "Visible pores, subtle skin grain, tiny tonal variations, slight natural shine, and minor unevenness.",
    "hair": "Several flyaway hairs and slightly tangled or displaced strands.",
    "clothing": "Minor wrinkles, natural fabric tension, tiny shifts in strap alignment, and realistic seams.",
    "environment": "Weak reflections, tiny scratches, surface wear, water droplets, fingerprints on reflective surfaces, or other understated signs of ordinary use where physically appropriate.",
    "image_artifacts": "Fine sensor grain, subtle JPEG compression, very mild motion softness in isolated moving details, and slightly imperfect smartphone sharpening.",
    "priority": "The image must feel less like a technically perfect AI render and more like a real photograph that happened to capture a particularly attractive moment."
