looks great man. somehow i really love the ununiform shapes of the buildings (even tho i realize these are most likely just drafts)
one thing that occurs to me, and could be me just understanding things wrong.. is that i believe there would need to be a much larger farm-network to support such a city... i could be wrong, but i think farmland usually needs to equal or surpass urban areas just to keep everyone fed... obviously not all of these areas need be on the map, and also trade routes could help with this.. so your map could easily be truthful, i just thought i'd point it out.
i think we've had the conversation before about the common lack of farmland associated with a city, maybe if you search around you might be able to dig up those threads... either that, or someone else could support my claim? or possibly kick me in the teeth and call me stupid? either/or would help shed more light.
