Cinematic Black-White Portrait

Create an ultra-realistic cinematic black-and-white portrait of a young South Asian man sitting in a dark, minimal indoor setting. He has thick, naturally messy textured black hair with slightly faded sides, a neatly trimmed light beard and mustache, sharp facial features, and a calm, deep-thinking expression.
He is wearing a plain oversized black T-shirt. His body is slightly turned toward the camera while his head is tilted downward and toward the right side. His right hand is raised near his mouth/chin, with his fingers gently touching his lips in a thoughtful pose. He wears a metallic silver wristwatch on his wrist.
The background is a dark plain wall, with a subtle vertical light area on the right side. Use dramatic low-key lighting, strong shadows, soft highlights on the face and arm, deep blacks, and a subtle vignette. The overall mood should feel moody, mysterious, emotional, stylish and introspective.
Composition: vertical portrait, medium shot from waist/chest up, subject positioned slightly left of center, lots of negative space, natural relaxed posture.
Camera: professional DSLR, 85mm portrait lens, f/1.8, shallow depth of field, soft cinematic focus, high dynamic range, realistic skin texture, detailed hair, natural shadows, fine film grain, monochrome black-and-white photography, high contrast, editorial fashion photography, ultra-realistic, 8K quality.
Important: Keep the person's facial identity, facial structure, hairstyle, skin texture and body proportions exactly as the reference image. Do not beautify or alter the face. Maintain the same pose, hand position, camera angle, lighting style and overall composition as closely as possible.
Aspect Ratio: 4:5, photorealistic, cinematic monochrome photography.
