Lots of paths around the flag which is nice, but too many big open areas where firefights are going to occur. The middle will be like a pp1 grass yawnfest. You need more vis-block-like clutter on the bridge, in the low middle, and in that area in front of the flag.
Also, a lot of the little trick jump high routes are cool, but totally unnecessary. With that ice in the low middle, I doubt anyone will ever use these. You need to think about the routes you're encouraging.
Right now the primary routes will be low ice-to that crate ramp jump-to high and high-to low ice-to flag.
This means a lot of people will camp right around the ice opening (which there is currently no easy way to jump over/get around streams) and also the high route opening (which suffers from the same problem as shazam22.bsp). Maybe your little in-wall side route will mitigate this, but it's hard to tell.
I would clutter up the middle, the base grass area and create little jumps to get over streams around the high/low middle openings. Also, I would try and give people a reason to not use the low ice to get to the flag (i.e. the other routes are just as fast/easy or there is something that stops your ice jump flying).
