Neon Valkyrie Guard in the Cybermuseum

Hyper-detailed cyberpunk Valkyrie standing in a grand museum hall that fuses ancient marble with neon-lit glass and holographic displays. She wears gleaming chrome-and-leather armor with a winged helmet, and retractable cybernetic wings extend from her back. Runic sigils glow electric blue along the armor as an energy blade hums at her side. The hall is alive with floating holograms depicting Norse myths, vitrines of relics, and drones weaving between marble pillars. Rain-slick skylights reveal a sprawling neon city outside while blue-pink neon reflections wash over polished floors. Cinematic lighting, ultra-detailed textures, 8k resolution, mood of awe where myth meets future technology.
