Generate an ultra-realistic, full-body 3D model of a middle-aged man with Mediterranean features: olive-toned skin, deep-set hazel eyes, slightly curved nose, and a neatly trimmed salt-and-pepper beard. His hair is thick, wavy, and shoulder-length, with subtle graying at the temples. He is wearing a dark blue tailored coat over a beige linen shirt, leather belt, and weathered brown boots. His posture is relaxed yet confident, hands loosely in his pockets, standing in soft natural sunlight that enhances the textures of his clothing and skin. The background is a blurred European cobblestone street.
