背对着你，只用一双眼睛回头。 Prompt: A real smartphone vertical photo shot at night with a direct on-camera flash, 9:16: a young Japanese woman in a miniskirt police cosplay is on a dark wooden park bench, photographed FROM BEHIND — her back is turned to the camera while she twists her head back over her left shoulder and looks straight into the lens, so a three-quarter view of her face with the eyes, nose and mouth clearly visible. Her torso leans back and twists at the waist, her right arm straightens downward with the palm braced flat on the bench seat beside her hip. She wears a dark navy short-sleeved cropped police shirt that leaves a strip of midriff and lower back bare, a gold "POLICE" shield patch on her right sleeve, a dark navy pleated mini skirt, a dark navy police cap with a black visor and a metal badge on the front, and a wide black leather belt with metal eyelets and a pair of silver handcuffs hanging at her right hip. The bottom edge of the frame cuts at the hem of the pleated skirt and the tops of her thighs, so the legs below are outside the frame. Behind and around her: a night park, black tree silhouettes, the dark slats of the bench, a distant blurry streetlamp and a dim paved path, everything else falling into deep shadow. The light is a bare direct flash from the camera: hard local highlights on her bare skin, on the shirt fabric and on the glossy skirt, crisp black shadow edges cast behind her onto the bench and the ground, and a very dark unlit background, typical of night mode with a flash. Real photographic texture: visible skin pores and a slight sweat sheen where the flash hits, real fabric weave and pleat edges, a few stray hairs lifting around the cap, mild sensor noise in the shadows, no beauty retouching, no illustration or 3D-render look.
