Create an ultra-realistic 4:5 vertical travel portrait using the uploaded image strictly for the male subject’s face and identity. Preserve exact natural facial features, face shape, proportions and likeness. Man stands barefoot on a large river rock beside a crystal-clear mountain stream, wearing a loose black oversized T-shirt, light cream cargo shorts and black baseball cap. He holds black sunglasses by one temple near his face, looking directly at camera with a calm, warm expression and subtle smile. Full body, both bare feet visible, centered foreground, relaxed masculine stance, slightly angled body, shoulders loose. High elevated downward angle, 28–35mm DSLR perspective. Background: turquoise transparent flowing water, smooth rocks, small cascading waterfall, visible riverbed, lush alpine shrubs, moss and yellow/white/purple/pink wildflowers. Soft overcast daylight, natural reflections/shadows, believable greens, peaceful wild atmosphere. Real skin/fabric/rock/water detail, no beauty filter, plastic skin or AI look, photorealistic 8K.
