Well... I think it's a pretty cool map as it. The layout looks quite ok, with even the suggestion of height worked into the map. I do miss labeling though? I think that would really add to the map. Maybe you could also add some fields or trees outside the city? One thing that I think is a bit weird, there seems to be only one road into the town? A town this large would probably have more visible road connections, probably one on the other side of the river.
By the way, it shows that you drew a large stone texture and then put the buildings on top. I rather prefer placing the individual streets and then houses, it somehow makes for a more realistic map I think. You might want to experiment with that when doing future maps.
