Towerbound Astronaut: Concept Art in a Spire

Concept art of a solitary astronaut inside a colossal futuristic tower. The astronaut, wearing a weathered white-and-orange suit, stands on a narrow spiral catwalk along the curved inner wall, tethered to a rail. A vast panoramic window reveals a distant planet and starfield. Soft dawn light floods the interior, casting cobalt blues and warm amber highlights across metallic panels, cables, and holographic glyphs etched into the walls. The tower blends art-deco and sci-fi aesthetics with brass rails, glass, and vented machinery. Camera angle is low and looking up, emphasizing scale and isolation. Painterly, high-detail matte painting style with cinematic mood and shallow depth of field. Extras: portable air recycler, tool belt, and a small drone circling overhead.
