Something else to think about: Where the roads & the buildings meet there is a a "haze" transition; I would imagine you have done some sort of outline or shadow to the roads, etc, but either way it is distracting--especially where some of the buildings are partly transparent--or where there are half buildings, etc.

Keep working on this. A nice map in process!

PS: I'm moving this thread from "Finished Maps" to "WIP/Critique", since that's what it turning out to be. I think Guildies will find it useful.
