Stellar Knight: A 3D Space Armor Render

Ultra-detailed, photorealistic 3D render of a medieval knight in outer space. The knight wears gleaming full plate armor with subtle sci-fi augmentations and blue energy filaments tracing the joints. He stands on a rugged metallic surface of an asteroid, with a distant blue planet and a vivid nebula filling the background. Dramatic directional lighting from a distant star creates sharp reflections on the polished steel, with volumetric glow and floating space dust. A plasma sword is strapped to his back, while a calm, resolute face is visible through a transparent visor. Cinematic, high-detail textures and realistic materials.
