Ok, what I like:

- The different icons you are using (the gates, bridge, salamanders, etc)
- The general layout of the city, although if I understand correctly, you can't take full credit for it of course
- Colors work pretty well together, although the palette is rather limited.
- The ridges, although I agree with Diamond about the suggested improvements.

Some of the stuff that needs some work I think:
- The structures look far too orderly. This might be more of a schematic map of course, but I like my city maps too look more realistic. So with houses crammed everywhere, large roads and tight alleys, market squares, docks, etc.
- I am sure there are better water textures out there. Or just give the water one bright color as a realistic texture wouldn't fit in. Not too fond of what you are using now.
- The font you used for the title looks ancient and not in a good way I think. It looks like fonts I saw in the eighties There are lots of great fonts out there.

You wanted feedback, so there you have it. The map is nice enough, don't be discouraged by my criticism (which might be a matter of taste as well).
