I love the sparse use of color against an otherwise "sepia" toned parchment. The only thing I might say to bring out even just a tad more pop would be for those foreground trees to get a very slight dodge on the sun side(or a burn on the shadow side, but I think I would prefer the former approach). I bring this up since it's fairly obvious(or perhaps it's just an illusion!!) but the sun side of the buildings really pop as being lighter than the parchment background...

Great map... but then again, I don't recall ever seeing one of your maps I did not like!
