Ultra-realistic conceptual portrait, 50mm lens, f/1.8, 8K resolution. Use uploaded face as reference-100% identical facial features, bone structure, natural skin tone, and expression. No modifications, brightening, smoothing, or distortion. A man stands centered, gripping a giant zipper running vertically down the middle of reality itself. Left side shows normal urban street scene in color; right side reveals dark cosmic void with swirling galaxies and stars. The zipper is metallic, oversized, partially opened. He wears a simple black t-shirt and blue jeans, pulling the zipper with both hands, expression of curiosity mixed with fear. Split lighting: warm golden hour on left, cool ethereal purple-blue glow from cosmos on right. Sharp focus on face and hands, background slightly soft. Hyper-detailed fabric, skin textures, metallic zipper teeth. Mind-bending, philosophical atmosphere. No text, no watermarks.
