Hey, that's a really nice city! I really like how the different worlds look so different with various colors. And 5500 people is a lot! Thanks a lot for sharing, I enjoyed looking at it (and at your other city as well!)
I'm not going to try to come up with a good name, I'm not great at that. But I'm sure you or someone else can come up with something great!
I think it's quite impressive that you found a citizen named Yehudi; there are 8887 possible names. :P
