1980s Cyberpunk Neon Movie Poster

An atmospheric 1980s dark synthwave action movie poster featuring a lone detective in his late 30s standing in a rain-slicked city alley, wearing a distressed dark leather trench coat over a high-neck dark sweater with sharp shoulder silhouette, holding an illuminated retro-futuristic handgun, his expression stoic and weary with rain drops glistening on his cheekbones, set against towering rain-drenched skyscrapers covered in kanji neon signs, glowing chrome billboards, and retro grid patterns, bathed in electric magenta, cyan neon, and deep midnight blue lighting with heavy rain mist and street light bloom reflecting off wet asphalt, captured in a towering cinematic movie poster composition with atmospheric depth layering, rendered in classic airbrushed 1980s cinema poster style with subtle VHS analog noise, grain texture, heavy shadow contrast, and classic sci-fi film noir mood.
