Ultra-realistic cinematic full-body portrait of a confident man (same face as reference image 100% accuracy), captured from a low angle with shallow depth of field. Straddling the snowmobile mid-start, right hand twisting throttle. Coat open, aviators reflecting glowing dashboard. Head turned 30° toward camera, determined half-smile. Snow dust kicking from rear tire. Outfit: long brown leather trench coat with loose belt, black t-shirt, dark blue jeans, sturdy brown lace-up boots. Lighting: warm golden-hour dawn from upper right mixed with snowmobile headlight beam. Background: blurred snow-capped mountains under indigo-to-gold sky. Palette: earthy browns, deep blues, blacks, cool whites, golden hues, evoking adrenaline dawn.
