Optimization! D: I don't know how you will do or did it, but it seems quite hard with all those low roofs! Some parts look bland and uninteresting too: it all follows the same basic colouring pattern and there is barrely any difference in style of buildings throughout the whole map. Just low buildings with pointy roofs all over the place. I'm sorry to say it like this, but I feel kind of dissapointed.
This might sound weird, but in my eyes it looks like a hammer shot, but .. with some basic lighting - if you know what I mean. Nothing stands out, nothing looks "FUCK YEAH THAT IS BADASS" exept maybe for the bridge. And that is why I don't like custom alpine maps. They all look pretty boring and none of them has ever even neared the fantastic feel and style of lumberyard. It isn't just about trees and grass.
Okay, time to end this rant, but i hope you'll try to make this map more special.
