悪魔と人間の分割顔ポートレート：劇的なコントラスト

"Create a highly detailed fantasy character portrait of a face split perfectly down the middle. The left side is a terrifying demon with glowing red eyes, cracked dark skin, sharp fangs, and subtle flames emerging from within. The right side is a calm, realistic human face with natural skin tone, soft lighting, and expressive eyes. The contrast between both halves should be dramatic, symbolizing inner conflict between good and evil. Cinematic lighting, ultra-realistic, 8K resolution, dark background, high detail textures, sharp focus, symmetrical composition."
