[Create an original ultra-photorealistic cinematic close-up portrait of a handsome young man with naturally textured, slightly tousled medium-brown hair. A few strands of hair fall casually across his forehead and face. He has realistic masculine facial features, subtle beard stubble, defined cheekbones, natural lips, and expressive light-colored eyes. Position his face slightly angled upward, with his gaze directed toward the upper-right side of the frame. A narrow beam of natural light enters diagonally from one side, selectively illuminating his eyes, cheekbone, nose, and parts of his hair while leaving the opposite side of his face in deep, rich shadow. Dress him in a lightweight white silk shirt with a relaxed open neckline. Capture delicate highlights and realistic folds in the fabric around the shoulders and collar. Create a dramatic low-key environment with an almost-black, softly atmospheric background. Use strong chiaroscuro lighting with a gradual transition between illuminated and shadowed areas. Preserve realistic skin pores, fine facial hair, individual eyelashes, detailed hair strands, natural eye reflections, and subtle lip texture without excessive retouching. Use the visual character of professional 85mm portrait photography at approximately f/1.4, producing very shallow depth of field and soft background separation. Maintain high dynamic range, realistic light falloff, natural skin tones, cinematic contrast, and refined editorial photography quality. Mood: mysterious, introspective, sophisticated, quiet, and emotionally powerful. Composition: vertical close-up portrait, face and upper shoulders filling most of the frame, no text, no logos, no watermark, no artificial-looking skin, no exaggerated facial features.]
