Ambitious indeed, and a great result for your first posted map! The city seems to make sense. I love the detail. Have some REP!
I might have liked to have seen some dirt roads rather than green grass on the villages in the outskirts and the patches of houses their look almost like crops. Almost too orderly. Also its difficult to tell if there are alleys or smaller streets carving out those swathes of buildings between the large roads. Still, too many city maps I see have vast spaces between buildings, when it should really be more like this map.
It would have been nice to visualize the missing alleys though. Still good job!
