Solitary Figure in a Noir Alleyway

In stark black-and-white, a solitary figure stands in a narrow urban alley under a flickering streetlamp. Rain-slick cobblestones reflect harsh light, casting long dramatic shadows along damp brick walls. High-contrast chiaroscuro with misty fog and subtle film grain for a vintage noir feel. The figure wears a long trench coat and fedora, face half-lit, eyes hidden in shadow, posture tense and alone. Perspective from a low angle to emphasize isolation, distant neon sign blur adding an urban ghostly vibe. Cinematic, monochrome textures on walls and rain, 35mm-esque depth of field with shallow focus on the figure fading into the moody background.
