Cinematic Red Blue Split-Light Portrait

Create an ultra-realistic cinematic close-up studio portrait of a {argument name="subject" default="confident young adult Black man"} facing the camera directly, centered in the frame against a completely dark black background. He has a short neat fade haircut, smooth skin with natural pores and subtle highlights, dark focused eyes, relaxed closed lips, and a calm powerful expression. Pose him with one hand thoughtfully under his chin, thumb along the jawline, showing a polished silver metal wristwatch with a black dial on the wrist. Dress him in a plain {argument name="shirt color" default="black"} crew-neck T-shirt. Use dramatic split lighting: saturated electric {argument name="left light color" default="blue"} light illuminating the viewer-left side of his face, hand, and shoulder, and saturated {argument name="right light color" default="red"} light illuminating the viewer-right side, with a subtle blend across the center of the face. Make the image feel premium, masculine, mysterious, editorial, and powerful, like a high-end magazine cover portrait. Use tight head-and-shoulders framing, shallow depth of field, crisp facial detail, realistic skin texture, glossy catchlights in the eyes, strong contrast, deep shadows, no visible text, no logos, no watermark, no props besides the watch, and no background detail.
