Graffiti Restroom Flash Portrait

Ultra-realistic 8K photo, gritty underground restroom covered in dense graffiti on all walls, raw urban aesthetic.
Extreme wide-angle fisheye lens, slightly tilted perspective.
A young person (use my face), sitting casually on a toilet, one arm stretched touching the wall, other arm bent above the head. Neutral, calm, slightly intense facial expression, direct moody gaze. Black cropped top, low-rise cargo pants, chain belt, silver jewelry.
Flash photography with harsh on-camera flash, high contrast, deep shadows, muted green and blue tones, film grain, realistic skin texture, candid street-photography style, cinematic realism, looks like a real photograph, no Al artifacts.
