Use the uploaded man’s photo as the ONLY facial identity reference.
Create a premium ultra-photorealistic professional studio portrait closely matching the supplied reference image in pose, clothing, framing, lighting and background.
FACE PRESERVATION — ABSOLUTE HIGHEST PRIORITY:
Preserve the man's real facial identity exactly from the uploaded photo.
Keep his original eyes, exact eye shape and spacing, eyebrows, nose, lips, mouth, cheeks, ears, forehead, chin, jawline, face shape, skin tone, real age, hairstyle, hairline, beard and moustache exactly unchanged.
If the uploaded man has no beard, moustache or glasses, DO NOT add them.
If he has them, preserve their original shape and style.
Do not beautify, reconstruct, reshape or redesign his face.
No face swap, no identity change, no artificial facial reconstruction.
