This is a whimsical digital illustration in fantastic style, with ultra-wide angle. Two giant pink crystal castles stand symmetrically on both sides of the background (the castles are made of transparent material, internal light, the surface is covered with vines and luminous love relief, and the material details are high-precision). In the middle of the sky, there are floating pink-purple gradient clouds (volume light fog effect, starlight particles and suspended love bubbles in the clouds, floating soft and floating), the foreground adds low translucent pink-purple clouds (volume fog effect, slight flow feeling, hierarchical transition with mid-view clouds), soft diffuse light combined with tindal light (global light GI high dynamic range HDR soft light), overall hazy dreamy atmosphere, depth of field blurring processing, 8K ultra high definition, movie-level rendering, Octane Render style, Cycles 4096 sampling, noise reduction,
