Aurora Acrobat Over Frozen Geometry

Vertical 9:16 poster, a masked carnival acrobat gliding across a wind-carved tundra beneath sweeping aurora ribbons, posed in a weightless spiral of motion with serene dream-energy, faceted low-poly 3D render, body and costume built from hammered copper planes with glowing seams, acid neon green and magenta illumination reflecting across ice crystals and frozen mist, long elegant motion trails sliced into geometric shards, surreal polar air filled with floating polygon sigils and crystalline arcs orbiting the figure, ultra-clean futuristic composition, high contrast negative space reserved for headline and emblem, pristine graphic balance, ethereal, refined, otherworldly spectacle
