Moody Rain-Slicked Noir Detective

A gritty neo-noir digital art concept illustration of a weary 40-year-old male detective wearing a classic beige trench coat with an upturned collar and a dark fedora, standing in a dark narrow brick alleyway during a heavy nighttime rainstorm, his face partially shielded in shadow while a glowing lit cigarette casts a tiny amber warm light on his stubbled jawline, holding a damp leather notebook while looking down at a glowing mysterious neon sign clue reflected in a puddle near his feet, surrounded by iron fire escapes, wet brick walls stained with graffiti, and distant dim yellow streetlights filtering through dense rainfall droplets and rising steam, lit with harsh cinematic low-key chiaroscuro lighting, cold cyan night atmosphere contrasted with subtle warm amber accents, capturing a tense mysterious investigative mood, framed in a medium full-shot composition with dramatic vertical leading lines, shot with an 85mm portrait lens at f/1.4 creating sharp subject isolation from the rain-blurred alley background, rendered in stylized digital painting art, heavy film grain, subtle motion blur on falling raindrops, deep moody dark tones, conveying a classic cinematic mystery atmosphere.
