I focused on a lot of layered designs based on the artist Gábor Eszenyi, who I’ve mentioned before. I really liked the idea of the central world being like the main hub or acting government for the rest of the minor cities around it.
These minor cities would be the ‘slums’ or lower classes of the world, like the slaves and servant quarters on a ship. They would be attached by long metal splints, acting as bridges. Transport could be normal like in the case of cars or trams, or by foot by those that couldn’t afford it.
For the main city shapes, I looked into the different architectures, nature and other aspects that were characteristic of Rome.
