Polaroid stairwell snapshot k idol style

1:1, Polaroid instant film, snapshot in a dim stairwell, cyan-green chemical color cast, white Polaroid border, low latitude. Adult young female around 20 years old, K-idol visual, small face with short philtrum, almond eyes with aegyo-sal, light pink lips, clear creamy nude makeup and realistic semi-matte skin texture; black hair casually tied in a high bun, messy and natural loose hair on the forehead and side of the ears. White tank top with a light blue denim jacket over it, the jacket sliding off one shoulder; the person stands at the corner of an old apartment staircase, walking sideways, suddenly turning back after being called by name by the photographer, mouth half-open, showing a clearly unprepared snapshot feel, holding a blue disposable lighter casually in the right hand. The photographer's fingers enter from the bottom of the frame. Close-up half-body diagonal composition, background is a gray wall, sharp diagonal shadows, and a dim staircase. Overhead light / close-up fill light illuminating the face and shoulder line, shadows are cyan-green, highlight edges slightly blurred.
