A realistic vertical mobile-phone selfie, 9:16 aspect ratio. A young adult woman in her 20s is inside a car under a panoramic sunroof. The camera is placed low, around waist or seat height, shooting upward. Her body is close to the lens, her head slightly lowered, and one arm extends upward out of frame as if holding the phone or adjusting the angle. The composition should feel slightly off-center and casual, not perfectly staged. She wears a worn gray baseball cap with a low brim hiding her eyes. The upper half of her face falls into the cap shadow, leaving only a soft facial outline, nose bridge, and relaxed closed lips visible. Her expression is calm, unsmiling, low-emotion, and slightly distant, like a casual photo taken right after sitting in the car. Long black hair falls naturally from both sides of the cap, with a few messy strands and real airy texture. She wears a white sleeveless high-neck cropped tank top with a large muted gray block-letter graphic print across the chest. The fabric looks like thin cotton or stretch knit, fitted to the body with subtle horizontal wrinkles and realistic stretch texture. The bottom is a low-waist white sporty skirt or shorts with folded fabric around the waist and a small black inner edge visible. The waist and abdomen are fully visible. Visible skin areas include the neck, shoulders, upper arms, edge of the underarm area, small collarbone area, full abdomen, side waist, and upper hip edge. Her skin tone is fair neutral-cool, slightly grayish in the shaded car interior, smooth but natural, as if cool to the touch, soft, with subtle pores and real underlying contours. The skin must be completely clean: no tattoos, no body markings, no text, no stickers, no patterns on the skin. Lighting comes from overcast daylight entering through the panoramic roof and car windows. The pale blue-gray cloudy sky outside is bright, while the black car roof and curved sunroof frame create strong negative space. The subject stays in the darker car interior; the cap casts a strong shadow across the face, while the shoulders and abdomen receive soft diffused sky light. Keep slight mobile noise, dark shadow compression, bright sky highlights, and a raw phone-camera feeling. Avoid studio lighting, commercial retouching, excessive skin smoothing, and an artificial glossy AI look. Negative prompt: tattoo, body art, skin text, watermark, logo watermark, over-retouched skin, plastic skin, studio lighting, mirror selfie, heavy makeup, extra fingers, distorted hands, bad anatomy, unrealistic body, AI glossy look.
