Neo-Noir 1920s Gangster Portrait

A highly structured prompt for Gemini Nano Banana Pro using image-to-image face influence to generate an ultra-cinematic, neo-noir portrait of a young male gangster from the 1920s. The scene is set on a wet, rainy night street, focusing on high contrast, deep shadows, and specific wardrobe details like a long wool coat and flat cap.
