Too open where it should be more confined; too confined where it should be more open.
I've seen few maps this open, and that's sometimes a bad thing but sometimes a good thing.
I don't really like the map layout. It's much too open for a melee map except in the middle, where the firefight would be, it's cramped. Your chokepoints are literally choked. You should try making some more space. Aside from that, it appears that there are very few resources. I'd have to download the map to know for sure, but my "new" laptop doesn't support the Map Editor. Other than that, this map is decent at best.
