This is indeed one of your best maps. Nice texture+scenery usage, this map shows us one basic rule that one tree looks ugly, but multiple use of trees looks great (someone calls them forests also). Those cave bgs could be less dark or you could set darker bg under those huge cave areas as shadow or something (there's atm standard bg). When bg doesnt change smoothy, I don't like it.
Nice to see you making map with flag throw option, and I like the fact that it's not only thing that map is build for (like IceBeam, HotBeam, Bone and such). With luck player could throw+shoot the flag very far to other side of map.
Waiting for maptest, I see potential in this one
