The tree looks sexy, but otherwise I don't like much about it. Maybe it's just me but those long curves don't match with jungle theme, so add some randomness/exceptions into curves. Chaos of polyislands, with typical flag and player spawns :S. The entrance for middle isn't too smooth.
As it is now, I think its too easy to escape already.
If you mean with too easy escape about high number of caps, then you are wrong. High number of caps is not a problem, except if teams get 10 caps in 5mins, which we can't talk about here.
If you mean problem of both flags stolen, then I see you are right. I guess there will be a lot of cat & mouse situations in this map. At least I hate the most in ctf play that situation (both flags stolen, hunt for efc), that's propably the thing why I don't like much about htf either.
