You have some missing light textures on the red side.
I dont think the flag will be easily campable. Camper has no place to hide behind. Even if 1 man is camping on the flag he will be easily killed. The lights (the textures) look a bit off in my opinion. Maybe find some other way how to light the map.
And barrels which are placed just next to another should have atleast as big cap as you can walk between them. Thats only my opinion though.
1 path maps rock. I didnt test the spawns, but I guess you spawn with barrels, but you could make some barrel jumps (like on top of those big ones) and as a reward you get a decent barrel. Brass lying around elsewhere. But thats up to you.
