Create a vertical 2:3 ultra-detailed anime fantasy illustration of one ethereal dancing woman surrounded by a dense storm of luminous crystal butterflies, flower petals, and magical light trails. The single female subject has {argument name="hair color" default="long flowing dark brown hair"} streaming dramatically to the left, a serene upward-facing profile, closed or half-closed eyes, and a graceful arched pose with both arms extended above and outward as if floating in music. She wears an ornate floral fairy-dancer costume made of countless jewel-like blossoms, translucent petals, vines, and sparkling filigree, with a flowing layered skirt that dissolves into ribbons, butterfly wings, and glowing floral fragments. Fill the entire frame edge to edge with hundreds of radiant butterflies and flower shapes in {argument name="color palette" default="electric violet, magenta, cyan, sapphire blue, gold, orange, and hot pink"}, with swirling circular composition lines wrapping around her body and hair. Use intense neon bioluminescent lighting, glittering highlights, prismatic glass textures, iridescent wings, golden threadlike arcs, star-like sparkles, and maximalist detail. The mood is ecstatic, magical, and dreamlike, like a celestial flower festival or butterfly nebula. Make the image highly polished, sharp, vibrant, and intricate, with no text, no border, no watermark, and no extra characters.
