Stylish Smiling Portrait of a Young Man

Create a highly realistic close-up portrait based on the reference image. A young South Asian man with thick, voluminous, naturally messy black hair styled with textured strands and a subtle fade on the sides. He has well-defined eyebrows, warm natural skin tone, neatly trimmed mustache and short beard, realistic facial proportions, and a bright genuine smile showing natural white teeth. He is turned slightly toward the right side of the frame, looking off-camera with a relaxed, confident and happy expression. He is wearing a loose white button-down shirt with the top buttons open and a simple gold chain around his neck. Capture the portrait from the chest up with a slightly angled camera perspective. Use a clean pure-white background, soft high-key studio lighting, natural highlights and subtle shadows, realistic skin pores and facial texture, detailed hair strands, realistic beard texture, natural teeth, accurate anatomy, and professional DSLR portrait photography. Keep the image photorealistic and sharp while maintaining a natural appearance. Important: Match the reference composition, hairstyle, facial expression, head angle, clothing, jewelry, lighting, proportions, and overall visual appearance as closely as possible. No text, no watermark, no extra accessories, no distortion, no artificial plastic skin, no excessive smoothing. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
