Create a Roblox-style 3D model of a final evolved spirit named "Wind King Crane" (풍왕학). Design a majestic crane spirit with sleek, elegant features and flowing feathers shaped like swirling winds. The body should be slender but powerful, with long wings and graceful curves. Use colors like soft white, sky blue, and faint silver accents. Add floating feather particles around it and a light wind aura that trails behind its movements. The model should look clean and collectible, not hyper-realistic, and optimized for Roblox performance. Focus on creating a bold and dynamic silhouette that feels swift and mystical.
