Well, atpollard seemed to cover the elevation issues and gave me a few insights I hadn't really considered before (thanks for that). The only one that struck me being the land being mostly flat in real cities generally, but not here. Other thing is there are only two gates and the one on the west side seems a bit odd. But could just be a quirk of the city so that is that. No apparent buildings outside of town though.

Apart from that, very nice and clean style. The map looks great. I think the fill on the buildings is fine myself but the outlines of some of them seem a lighter grey than the others? I don't know why that is.
