Incorporate 3D elements such as shimmering gold geometric patterns, elegant glass reflections, and floating design elements to enhance the luxury feel. The color theme should be Black, Purple, and Gold, with subtle gold highlights adding a premium touch. Ensure smooth transitions and mesmerizing light effects to maintain a high-end, cinematic look.
