Night Pool Flash Portrait Beauty

Vertical 9:16 Realistic Night Pool Flash Portrait. A young adult woman sits by the pool at night, with a high-angle close-up of her whole body, with her face and most of her legs naturally framed. Her eyes shine brightly at the camera, with clear eyes and a naturally cheerful smile, as if she's being photographed by a friend with a phone flash.

She wears [swimsuit style/color] with realistic fabric textures and subtle water droplets. Hairstyle: [Twin Ponytails / Wet Long Hair / High Ponytail / Soft Wavy Hair]. She sat slightly to the side, gently twisting her upper body toward the camera, relaxed shoulders, naturally raised chest, with a defined waistline and smooth hip curves. Stretch one leg forward and slightly bend or gently cross the other leg for a relaxed and elegant full-body poolside pose.

The background is deep blue pool water, with visible ripples and reflections of white light, surrounded by damp stone bricks. The main body features a cool white direct flash, while the background is a deeper blue pool, with realistic skin textures, natural moisture, slight graininess, and a realistic camera feel.

Avoid stiff expressions, hollow eyes, weak smiles, plastic skin, excessive smoothing, shiny faces, CGI effects, twisted hands, wrong fingers, twisted legs, wrong toes, exaggerated feet, deformed swimsuits, stiff postures, overexposure, cartoon or illustration styles.
