有機建築與生物發光樹的烏托邦城市

9:16 aspect ratio, cinematic, hyperdetailed, photorealistic. A breathtaking city where architecture and nature are one. Gleaming, organic-looking white spires are seamlessly intertwined with massive, living, bioluminescent trees and vibrant flowering vines. A crystal-clear river flows through the city's center, with graceful, bridge-like roots arching over it. In the warm, golden light of sunset, the city's inhabitants—humanoid figures in elegant, simple clothing—walk peacefully along the pathways. The entire scene is one of perfect harmony, advanced biotechnology, and serene, sustainable beauty. The atmosphere is utopian, hopeful, and awe-inspiring.
