Neon Banshee in an Ice Cavern

In an ice cavern lit by neon cyberpunk signage, a banshee hovers, semi-transparent and ghostly, with cybernetic embellishments: glowing circuit patterns on her translucent skin, chrome fractures, a halo of holographic data around her head, and jagged cybernetic wing-like fins along her back. Her eyes glow cyan-green; frost breath streams from her lips as she emits a wail that ripples through the crystalline air, turning into pulsating ribbons of electric blue and magenta. The cave walls are blue ice with crystalline texture, stalactites dripping frost, and reflective pools that mirror the neon glow. Floating holograms, digital runes, and faint rain of ice shards drift around. The scene is moody and cinematic, with high-contrast lighting in purples and cyans, a fusion of cyberpunk and dark fantasy, ultra-detailed, painterly digital art.
