Mystical sorceress at the threshold of a crystalline realm

A mystical sorceress stands at the threshold of a crystalline realm, her frost-kissed skin glowing ethereally as neon lights and auroras dance across her being, infused with winter's mystique, amidst cinematic lighting casting a golden glow on icy landscapes, delicate frosty filigree, icy spires, and subtle starlight, her long silver hair flowing like a river of moonlight, surrounded by a halo of frosty mist, and an icy crystal staff in hand, radiating an otherworldly aura, as if the very essence of winter has been distilled into her being.
