Reference: the man in the image I uploaded. Keep his facial structure, hairstyle, beard density and style of glasses identical, so his identity stays fully consistent.

Pose: he stands in a dark studio in a fitted black turtleneck sweater. With his left arm he keeps a silver laptop, closed, pressed naturally to his torso, while he bends his head a little toward the wristwatch on his right hand, as though checking the time.
Expression: calm, focused, intellectual.
Light: dramatic low-key light from camera left, giving strong contrast and a gradual shadow falloff over face and body.
Background: clean and black.
Detail: sharp skin texture, realistic fabric folds, cinematic shadow gradation.
Style: ultra-realistic cinematic portrait, professional editorial photography, shallow depth of field, the look of an 85mm lens.
Output: ultra-high resolution, 8K, vertical 4:5 composition.
