Modify the man in the reference image: make his mouth completely closed with a calm, natural facial expression (no open mouth/visible teeth), and add neat, well-groomed masculine stubble / short beard shadow across his jawline, chin, and cheeks. Keep the exact same identity, face structure, dark sunglasses, hairstyle, blue outdoor trekking jacket, dark inner shirt, pants, hiking pole, and the entire background with the turquoise mountain lake, misty pine forest, morning sunlight rays, and snowy alpine peaks intact and photorealistic.
