A bustling underwater cityscape, glowing with vibrant neon lights, where a deep-sea diver navigates through streets filled with playful, jellyfish-like creatures. These creatures have translucent bodies, swirling bioluminescent patterns, and tentacles that flicker gently in the currents. The buildings around them are fluid and organic, with curves and spirals reminiscent of Gehry and Gaudí’s architecture, blending seamlessly into coral reefs. Schools of fish dart between the structures, while the soft, ambient light from the ocean surface filters down. The scene is richly detailed, with a macro lens focusing on the diver and the creatures, showcasing intricate textures and cinematic lighting in a dreamy, futuristic environment.
