ultra-realistic cinematic portrait of the same young man

Create an ultra-realistic cinematic portrait of the same young man from my uploaded photograph, using my uploaded personal photo as the ONLY identity reference with strict identity preservation—retain the exact face shape, facial proportions, eyebrows, eyes, nose, lips, jawline, natural skin tone, beard pattern and all recognizable facial details without beautification or facial modification. The subject is sitting casually in a dark indoor room beside a large window, positioned slightly toward the left side of the frame, wearing an oversized textured olive-brown button-up shirt with the top buttons undone and relaxed black trousers. One knee is raised prominently toward the camera, his left hand rests naturally beside his body, and his other arm extends toward the right side; his head is turned toward the right with a slightly upward angle, gazing thoughtfully toward the window with a calm, introspective expression. Give him thick, naturally messy, voluminous dark black hair with soft waves and loose strands falling across his forehead. Create dramatic golden-hour sunlight entering through the window on the upper-right side, producing beautiful warm golden rim lighting around his hair, cheek, neck and shoulders while leaving the opposite side in deep cinematic shadows. Keep the background minimal with dark brown curtains and a softly illuminated window. Use a warm amber, deep brown and black color palette, subtle vintage film grain, realistic skin texture, natural fabric details and beautiful chiaroscuro lighting. Camera: Professional DSLR photography, 50mm portrait lens, slightly low eye-level perspective, medium full-body seated composition, shallow depth of field, vertical 9:16 framing, ultra-photorealistic 4K quality. Negative prompt: Different face, identity drift, altered facial structure, artificial facial features, beauty filter, plastic skin, excessive smoothing, wrong beard, straight hair, different hairstyle, incorrect pose, extra fingers, deformed hands, distorted anatomy, overexposure, flat lighting, cartoon, CGI, 3D rendering, watermark, text, logo. Final result should look like an authentic premium cinematic photograph, not an AI-generated image. Face identity must match my uploaded photograph exactly; only the pose, outfit, environment and lighting should change. 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.
