ネイビーブルーのスタジャンを着ている若い男性

"A realistic portrait photo of a young man with dark, thick curly hair and a light trimmed beard and mustache, smiling warmly at the camera. He wears a navy blue varsity jacket with cream-white leather sleeves, yellow chenille embroidered lettering on the chest, white snap buttons, and blue-and-white striped ribbed trim at the hem. Underneath is a black t-shirt with a thin silver chain necklace. He stands with his hands in his jacket pockets, body slightly angled, on dry golden-brown grass beside a rocky riverbed. Behind him, a clear river flows over white and grey stones, with bare winter trees and a hazy mountain range with snow-capped peaks under a bright, clear blue sky. Natural daylight, crisp winter sunshine, shallow haze in the distance, candid lifestyle photography style, shot on a smartphone, vertical 4:5 aspect ratio, sharp focus on the subject, vibrant but natural colors."

**Tips:**
- Add *"photorealistic, 85mm lens, shallow depth of field"* for a more professional look.
- To change the mood, swap in *"golden hour lighting"* or *"overcast soft light."*
- If you're generating a different person, keep the clothing, pose, and setting details and describe the new face separately.
