Ultra-realistic full-body action portrait of a stylish young man (same face as reference image 100% accuracy), captured eye-level with shallow depth of field. Walking down white marble stairs mid-stride, right foot forward, left hand swinging naturally, right hand lightly touching railing. Head turned 30° toward camera, confident half-smile. Dark square sunglasses, neatly trimmed beard and mustache, styled dark hair. Outfit: vibrant red t-shirt under crisp white short-sleeved collared shirt, sleek black slim-fit pants, white high-top sneakers with red and black accents, black watch flashing. Lighting: bright soft natural daylight from front, motion blur on background. Background: blurred marble stairs and golden railing streaking vertically. Palette: crisp whites, bold reds, deep blacks, golden warmth, creating a sleek urban momentum mood. At the bottom corner, add an elegant handwritten signature that reads ToolCookie.
