Hehe, this map is very original !
I really like how you embedded this architecture into nature, gives it a very natural feel, also the sound entities are very nicely done and placed, too. Neither too weak or too strong, just right.
It looks like it took you some time to make this map, also the surrounding landscape is looking good, the textures are a matter of taste of course, personally i dont like them too much, but i know how hard it is to find good looking textures in the sauer package, at least for such a big map, and all in all they fit well together and you also stayed in theme.
Lighting is ok, no reason to complain here. Some trees are standing a bit too close next to each other and to the geometry, some are unlit, too.
About playability i can´t really say much, but i think it should be ok to play with a medium amount of players in ffa, maybe 8+.
Also not sure about the capture part, 10 bases is a bit too much, maybe.
Maybe you could use more of the clip material next time, clip the fence for example, and the ladders from behind.
Because it looks so nice and you had so many good architectural ideas, i´ll give you
4/5 ;)
