Dr Doom

Use the uploaded image as the exact visual reference. Create an ultra-realistic cinematic portrait of the same person, split perfectly vertically down the center of the face.
Left half: preserve the person's real facial identity, natural skin texture, forehead, eyebrow, eye, nose, lips, moustache, beard, jawline, hairline and facial proportions exactly as shown in the reference. Intense serious expression, highly detailed realistic skin pores and natural imperfections.
Right half: transform the corresponding half of the face into a futuristic dark armored warrior helmet/mask. The armor should be matte black, heavy metallic, angular and battle-worn, with realistic scratches, dents, subtle moisture and fine surface texture. Keep the helmet geometry precisely aligned with the person's facial structure. Add a glowing emerald-green eye on the armored side.
Composition: extreme close-up head-and-shoulders portrait, perfectly centered symmetrical split, straight vertical division through the exact middle of the face, both halves matching in scale and perspective. Dark black outfit/armor around the shoulders.
Lighting & atmosphere: dramatic cinematic lighting, deep shadows, strong emerald-green rim lighting, subtle green atmospheric particles and haze in the background, dark futuristic environment, high contrast, moody sci-fi/dark-fantasy atmosphere.
Quality: photorealistic, ultra-detailed, realistic skin pores, physically accurate metal reflections, sharp facial details, cinematic depth of field, HDR, professional movie-poster quality, 8K detail, vertical 9:16 composition.
Important: Do not change or beautify the real face. Preserve the person's recognizable identity exactly on the human side. The split must be clean and seamless, with the armored half naturally connected to the real face.
