Art style: Crystal.
A tiny golden butterfly made of pure light appears in front of Lumi. She watches it with wonder. Crystal trees glow softly around her. Elegant crystal princess with luxurious blonde hair, deep neckline crystal dress, slim waist, graceful feminine figure, magical atmosphere, cinematic fantasy.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image in the following art style:
3D animated cinematic — characters and key elements rendered as glowing translucent crystal (faceted geometric structures, jewel-toned amethyst / sapphire / emerald / topaz palettes with tiny luminescent particles inside). Hyper-realistic material rendering: subsurface scattering, glowing internal luminescence, beautiful refractions, ray tracing, shallow depth of field. Pixar / DreamWorks-grade polish, 8k Octane / Unreal Engine 5 render quality.
Every surface, skin, fabric, material, and environmental element must be rendered in this idiom.
