A minimalist 3D render of a floating city that feels like Serenity. Perfect white geometric spheres and flat discs floating in a gradient beige-to-soft-blue void. Each platform holds a single bonsai tree made of glowing jade. No visible supports; everything is suspended by invisible forces. A single, gentle waterfall flows from the city down into nothingness. Ray-traced soft shadows, ambient occlusion, clean topology, 8K, Apple design aesthetic.
