Monochrome Rooftop Noir Portrait

Photorealistic black-and-white portrait of a man sitting on a gritty rooftop ledge in an urban setting at dusk. The subject is in his 30s, wearing a dark leather jacket over a simple tee and dark jeans. He sits with elbows on his knees, hands loosely clasped, gazing pensively to the left. The rooftop features rough concrete, a rusted vent, and a low parapet. Behind him, a dense city skyline of tall buildings with a dim, overcast sky. Use high-contrast monochrome lighting with a hard key light from the right casting dramatic shadows on the left side of his face, plus a subtle rim light along the jawline and shoulder. Add light rain for speckled highlights, film grain, and a gentle vignette to evoke noir mood. Overall tone: solitary, introspective, cinematic.
