my first two thoughts
1: Neat looking!
2: Where do I build?
The first big problem I see is the smooth slope between the areas where you can build and the walking path. Its hard for the eye to seperate them since the slope is so smooth. On the regular map its easy to see where you can build because of grass areas with the sharp edges around it made out of stone. So you both have the color difference and the hard edge.
I value that you are trying to add some eyecandy, but there is a very thin line between too much eyecandy and a usefull UI.
1: Make the slopes razor sharp again. This is the main reason I think its hard to see where to build.
2: No trees between infront of a builing area. The ones infront of area 7 is a good example. Either keep the trees to a short size, or keep them to the north side of a building area. South of a building area tends to block the view.
3: Be carefull with adding too many doodads. Fixing 1+2 might mean that doodads aren't that big a problem.
Lastly, the new icons. They are beautifully made, i'm worried they aren't iconic enough but that might be that I just need to get used to them. Maybe all that is needed is to tone down the colors behind the symbols a little bit. To make a bigger contrast between the symbol (arrow/shield/ect) and the background.
