Cinematic Black Leather Executive Portrait

Create an ultra-realistic cinematic studio portrait of subject seated confidently in a premium black leather armchair against a deep matte-black studio background. The subject faces the camera directly with a calm, composed, professional expression, short neatly trimmed black hair, clean-shaven face, and natural skin texture. Dress him in a crisp white long-sleeve dress shirt, fitted black waistcoat, slim black necktie, black dress trousers, and a silver metal wristwatch with a black round dial on his right wrist. Pose: relaxed but authoritative, torso angled slightly toward camera, right forearm resting on the chair arm with the hand near his lap, left arm relaxed with the hand resting on the seat edge, legs casually apart. Use a medium three-quarter seated crop from upper thighs to head, centered composition, portrait orientation. Lighting should be high-end studio photography: soft key light from front-left, gentle fill on the face, subtle rim separation, controlled highlights on the leather chair, and smooth falloff into the black background. Make the image look like a premium executive portrait shot with a professional full-frame camera, sharp facial detail, realistic fabric folds, glossy leather texture, shallow depth of field, natural color grading, no visible logos, no text, no watermark.
