So far most of the kits are pretty grounded, however I envision a captivating "utopian" metropolis "in the air", drawing inspiration from the vibrant essence of Asia.

This futuristic city would push the boundaries of vertical expansion, with towering blocks that seem to stretch into infinity. Amidst this breathtaking skyline, the cityscape would seamlessly integrate elements of nature in the buildings. (to give that utopian feeling)

Bridges and intricate structures would interconnect the buildings. Imagine a place where futuristic vehicles gracefully soar through the air, and the ground remains an enigma.

Something like this photo, It's true that you can combine several kits to do something similar, but I think that making a kit designed for a city with streets "in the air" and flying cars instead of a city with normal/modern streets would be something interesting.
