Heres another great example of someone that goes to the max! kirakiraouji has built the City of Maikura which is a Japanese metropolis.
In this project you will find a lot of well design elements put together to build this amazing city. There is a lot we liked there, the buildings, airport, cars, highway, shops, streets, etc. Everything looks well done and can’t imagine how long it took to complete. Hope you enjoy this project and are able to add it to your world.
