Create an ultra-realistic professional DSLR close-up portrait of a young man with warm, naturally textured skin and striking light brown eyes.Pose and Expression: He is looking off-camera to his left with a calm, intense, and thoughtful expression. His mouth is completely closed with his lips gently pressed together, and absolutely no teeth visible under any condition.Outfit and Accessories: A solid black collared button-down shirt, worn slightly open at the neck, revealing a thin silver chain necklace.Hairstyle and Grooming: Thick, dark, highly textured curly hair falling naturally and softly over his forehead. He has a subtle, light moustache and faint, natural stubble on his chin. Ensure there are absolutely no tattoos on his neck, chest, or body.Background and Lighting: A dark, moody, pure black background. The lighting features highly dramatic, cinematic chiaroscuro. A sharp, distinct beam of warm, golden sunlight cuts directly across his face, intensely illuminating his eyes and the bridge of his nose while casting the rest of his face, jawline, and neck into deep, rich shadows.Camera and Composition: Vertical tight close-up portrait (head and shoulders), eye-level angle, 85mm macro lens, incredibly sharp focus on the illuminated eyes and natural skin pores, perfectly capturing the striking contrast between the bright sunlight and dark shadows.Important: Ensure the mouth is strictly fully closed with no teeth visible. Ensure there are absolutely no tattoos anywhere. Avoid artificial skin smoothing, filters, or distorted anatomy.Negative Prompttattoos, open mouth, visible teeth, smiling, cartoon, illustration, painting, low resolution, blurry, distorted anatomy, extra fingers, artificial skin, flat lighting, bright daylight, plain lighting.
