Prompt: [upload image] Transform this attached marble sculpture into a hyper realistic, modern photographic portrait while preserving all recognizable facial structure and historical features. Render the subject as if immortalized through ultra detailed large format photography. Maintain the expression, bone structure, and iconic attributes, but reinterpret them with lifelike skin texture, cinematic lighting, and natural depth. Use photorealistic pores, subtle imperfections, and historically accurate complexion. Add soft volumetric light, shallow depth of field, and a timeless, regal atmosphere. Avoid stylization; aim for museum grade realism, as if the emperor were alive today.
