Дима提示Add realistic stubble facial hair to the man's face. The stubble should be natural-looking, evenly distributed across his jawline, chin, and upper lip area, with a medium density that suggests 2-3 days of growth. Match the stubble color to his hair color, ensuring it appears naturally shadowed and textured. Maintain the original lighting, skin tone, and all other facial features exactly as they are. The stubble should enhance his masculine appearance while looking completely natural and well-groomed.
