That's a very "neat" city. It's wonderful if you can get all the various facets of the citizenry to keep it that way. Buildings will burn or just fall down and others will be built perhaps not so neatly. I also concur with the above comments on the layout. Of course it is your city and perhaps your nobles and leaders of commerce need to be nearby to keep the rabble from stealing and causing mayhem. I like the "block" idea of depicting buildings without having to draw each building individually. These blocks can be color coded to represent different uses. Overall you have put a lot of thought into this and I wish you good luck. City mapping is it's own insanity. Trust me I know....
