A realistic smartphone-style outdoor vertical portrait, 9:16 aspect ratio

A realistic smartphone-style outdoor vertical portrait, 9:16 aspect ratio. The image shows a young adult woman positioned on a rooftop or terrace, sitting or leaning sideways with her body angled toward the right side of the frame while her head turns back toward the camera. The camera is close, cropping from the head down to the shoulder, upper arm, and a small upper-chest edge. Her right upper arm appears close to the foreground and creates a strong vertical cropped shape. Keep the subject slightly off-center toward the lower-right, with a casual, imperfect candid composition.

She has long, naturally black straight hair with full volume, falling over her shoulders and back. A few thin strands are blown by the wind across her cheek, eyes, and near her lips, partially covering the face. The hair should look smooth but not overly controlled, with subtle flyaways and natural frizz. Her face is small and softly oval, with clean brows, dark calm eyes looking into the camera, and naturally closed muted rose-red lips. The expression is quiet, restrained, and slightly distant, without an obvious smile. Makeup should follow an East Asian cool-girl soft beauty style: thin natural base, cool fair matte skin, soft straight brows, muted pink-brown eye shadow, delicate eyeliner, subtle under-eye softness, and blurred rose lips. Avoid heavy makeup.

She wears a white sleeveless camisole or tank top with small ruffled edges on the shoulder straps. The fabric is light, clean, and softly reflective under daylight. Visible skin includes the face, neck, right shoulder, right upper arm, a small collarbone area, and a restrained upper-chest edge. The waist, hips, legs, back, and buttocks are not visible. Her skin is very fair and cool-toned, with a faint soft pink cast on the face, while the shoulder and upper arm are brighter under sunlight. The skin should look delicate, clean, and slightly matte, feeling soft, cool, and smooth to the touch. Avoid glossy, oily, or plastic over-smoothed skin.

The background is a clear outdoor rooftop scene. A large pale blue sky fills the upper part of the frame, with a few small white clouds in the upper-right corner. Below is a dark gray rooftop parapet, a white cylindrical ventilation pipe on the left, and distant metal railing lines. Lighting is real daytime natural light: blue sky bounce creates cool ambient fill, sunlight from the right brightens the shoulder and upper arm, while the face remains softly shaded by hair and angle. The photo should feel like it was taken with a smartphone main camera or compact camera at close distance, around a 24–35mm equivalent focal length, with moderate depth of field, slight sharpening, mild compression traces, real hair obstruction, bright sky edges, and imperfect framing.

The mood is cool, quiet, and slightly detached, like a gust of wind had just passed on a summer rooftop. She has just turned back after being called, and the silence from the previous few seconds still lingers in her eyes; in the next second, she may look away. Do not make it look like a polished commercial studio portrait. Avoid over-retouching, oversexualization, fantasy styling, or anime aesthetics. Preserve the natural human-shot accidentality.
