Use case: photorealistic-natural Asset type: portrait image, intended aspect ratio 9:16 Primary request: Japanese negative film aesthetic, small balcony in summer, soft natural light, slight overexposure highlights, low contrast, faded colors, subtle grain. A fictional adult Korean female idol in her early 20s, refined and quietly magnetic, subtle sensuality through relaxed breathing and weight shift. Scene/backdrop: narrow motel balcony with a pale curtain drifting through the door, distant low city roofs, plastic bag and room key on a small metal table. Subject: leaning against the balcony rail with one hand behind her, torso angled toward open sky, hair moving over one eye. Wardrobe/props: peach oversized cotton shirt loosely unbuttoned at the collar, white high-waisted shorts, cold glass bottle of mineral water lifted near her lips. Composition/framing: tall vertical crop, slightly too close at the top, raw film snapshot feeling. Lighting/mood: morning haze, intimate but non-explicit, quiet. Constraints: fictional adult subject only; no real celebrity likeness; no visible brand marks, no text, no watermark.
