Witch in Zero-Gravity on a Space Station

3D-rendered, photorealistic scene of a witch aboard a space station. A sleek, high-tech corridor with chrome panels, glass lighting, cables and control dials. A starfield and distant nebula visible through a large viewport. The witch wears a flowing cloak with glowing sigils, a hood casting shadow over sharp features, anti-gravity boots, and a staff that doubles as a wand with a crystalline orb. She conjures a blue-green magical sigil that floats in zero gravity, surrounded by luminous motes and energy streaks. The environment uses physically based rendering with volumetric fog and dramatic cyan-magenta lighting. Small floating reagent crates and a holographic spellbook drift around, enhancing the sci-fi witch aesthetic.
