He wears black sweatpants and no visible socks or shoes. Lighting is dramatic, coming from above against a dark background with subtle shadows defining the muscles. Warm skin tones stand out against neutral colors, creating an intense and focused mood. Portrait orientation in 1333:2000 aspect ratio (832x1216 canvas)
