A dystopian neon apocalypse, where a colossal, vibrant smiley flower made of Geeky Liquid Marble toon looms over the end of the world. The environment is ultra-detailed, with vibrant colors and dramatic lighting highlighting the surreal, decaying landscape. No humans, only the flower's eerie glow illuminating the scene. Cinematic, 3D-rendered, and hyper-realistic, blending absurdity with photorealistic beauty.
