Young Man with Guitar

Use the uploaded background image as the exact background. Add the same young man naturally sitting beside the guitar, with the guitar resting naturally against his body as if he is sitting with it. He is barefoot, I wear a sky-blue striped full-sleeve shirt with folded sleeves, white pants, and white sneakers. He is looking naturally toward the opposite side, not at the camera. Keep his face, hairstyle, skin tone, body proportions and identity unchanged. Match the original lighting, shadows, perspective, depth of field and color grading perfectly. Make the final image ultra-realistic, natural DSLR photography, sharp subject, realistic skin and clothing texture, cinematic depth, 8K quality.
