Umweltporträt: Biker in Leder

A rugged motorcycle rider in his mid-thirties, short dark brown hair with a light stubble beard, deep green eyes, tanned weathered skin, no makeup. He wears a black leather biker jacket with silver zippers over a charcoal henley shirt, dark indigo jeans and scuffed leather gloves, leaning sideways on a matte black vintage motorcycle, one boot on the peg, arms crossed with a calm confident half-smile, squinting slightly in the light. Background of a raw concrete industrial garage wall with blurred tools and a red tool cabinet. Harsh directional afternoon sunlight from the left, golden-hour quality, raking across his face, casting long crisp shadows, strong contrast. Main palette of black, charcoal, rust brown and warm amber. Medium close-up, low three-quarter angle, gritty film-like texture, 4k
