Stern male portrait with frontal and profile views on white

Create a portrait of a massive man with a hard, closed face, marked by a strong bone structure and a stern expression. His forehead is straight, topped by a short, unevenly cut fringe, reinforcing his rugged appearance. His furrowed brows and narrow, piercing eyes betray a constant vigilance. His thick sideburns extend down to his jaw and frame his square face, accentuating his authoritative air. His nose is robust, and his tightly pressed lips express restraint and determination. The style should be clean, with crisp lines, including both a frontal and a profile view, all against a white background. No additional decorative elements: only the face, powerful and monolithic, and the impression of contained inner strength.
