It's cool, but it's way too big- both in terms of size and complexity. It's very long, and red have so long to snipe and harry at blu that blu finds it very hard to put up full strength at the end.
I think difficulty is a little geared towards defense- that hill is kinda tricky at the second point. I might recycle that point into stage 2, if i were you. Alternatively, removing some or one of the good sentry positions at the end.
The door that leads out next to the second point, on the left from blu's perspective, is very small and i never was able to do much from it because i constantly got spammed away from it. Widening it, or perhaps moving it direct to the point could help. Remember on dustbowl blu have a nearly completely covered, largely one-way route almost direct to B.
