Interesting map, I really like the detail you put into it. However, there are some concerns I'd like to raise. I feel like the spawns are much too close together for both teams. I also feel like this map favors ranged heavily and will frankly be a nightmare for infantry, especially when the archers are on the rooftops. Also there are a lot of stretched out objects, a big tree, and terrain that takes away from the overall look of the map.
I just feel like the only part of your map people will be using is the buildings, which may have been your purpose. However if that is the case you might want to make it easier for infantry to access the roof so that the archers don't have a field day. More stairs, less ladders that make infantry easy picking and less ledges to have to jump over. I think you need to tweak the spawns to be farther apart, and so that they allow people to go somewhere else on your map besides the buildings.
Overall, I like the idea but I feel like there are a few problems present. Don't take it the wrong way, I really like the attention to detail in the map.
