Ultra realistic cinematic portrait of a young man

Use my uploaded photo as the ONLY identity reference and my uploaded background image as the ONLY background reference. Preserve the subject's exact face, identity, skin tone, age, hairstyle, and natural features. Recreate the scene with the subject standing casually on the lakeside wooden deck, leaning lightly against the railing with both hands, one leg slightly crossed, looking toward the mountains. Match the background, mountains, lake, railing, lighting, and composition of the uploaded background image. Dress the subject in a simple black T-shirt, light beige loose-fit trousers, blue sneakers, and a black watch. Keep the body healthy and naturally proportionate according to the face-normal build, not thin or skinny. Ensure the output is photorealistic with natural skin and realistic hands.

Output: 4:5 portrait ratio (mandatory), 1080×1350 or higher. 9:16 is strictly prohibited.
