This map looks pretty much finished. Gameplay seemed alright, although the heights were excessive at times and sentries could lock down areas on the tip of their sight range.
Every time i entered the middle my game minimised with a GPU overheating warning window. My card is slightly damaged but i still manage to play TF2 (and all the official maps) without any problems so i'm not sure what optmisation methods you have in place but you might want to think about that more since comp players generally have shit computers and run fps configs to that affect. That said, my fps was pretty consistant without any spikes (or maybe that was just the lag cancelling out the fps spikes).
This is probably one of the most class balanced maps i've played that is being submitted to the contest that isn't also really small and boring. Loads of options available to players of all classes, if not a little scout friendly at times.
The theme is really nice if not a little odd/different; i'd say you only just get away with the humoungous trees. On a final note the texture usage is a little monotonous in areas and the buildings unnaturally tall and bulky for wooden structures, and red's buildings don't seem warn down enough.
My only gripe is that that intel is just randomly sat out in the open, along with a lack of spytech or locker room sub themes, but i guess if sawmill does that you can too.
edit: Oh, and i forgot to mention it, although i did say ingame, sometimes the fog looks off inside buildings and even interferes with team recognition in the most extreme of circumstances, 2fort uses triggers in doorways to set new fog colours and distances, i'd deffinately recommend this technique for your map too.
