Film noir portrait prompt

A film noir black and white portrait of a young man with dark, tousled hair falling over his forehead, sitting with his head tilted, gazing directly into the camera with a cold, brooding expression and sharp, angular features. He wears an all-black suit with an open-collar black shirt underneath, one arm resting casually with a glass of whiskey held loosely in his hand, a wristwatch visible on that wrist. He sits on a city street at night, with soft, glowing bokeh lights from streetlamps and distant neon signs blurred heavily in the background, creating circular halos of light against deep black shadow. The lighting is low-key and dramatic, with a single hard source carving sharp highlights across his face and leaving the rest in deep shadow, classic chiaroscuro film noir style. Shot on a full-frame camera, 85mm lens, very shallow depth of field, high-contrast black and white film grain, moody cinematic portrait, portrait orientation.
