Film-Noir-Porträt in Gasse mit Split-Lighting

A medium shot of a stern-faced man with the exact facial features, hairstyle, and glasses from the reference photo, standing silently at the entrance of a dimly lit alley. He wears [a black shirt and a classic long black overcoat], the dark fabric nearly blending into the shadows. One hand hangs down, gripping [a pistol]. The narrow alley recedes into deep darkness behind him. Shot in high-contrast black and white with a classic film noir aesthetic. Centered composition. Lighting: harsh overhead chiaroscuro lighting with no visible light source, splitting his face and body cleanly in half with bright light while the other half remains submerged in shadow, leaving the background tone untouched.
