just had a quick gander at it, my first impressions:
- you have a fair few misaligned brushes. The ice ramp at the blue side at the top. The outer wall in the water on the blue side. etc... if you need screenshots let me know.
- r_speeds with reflective water are very high, ~4000 at one point.
- what are the shards of wood about in the water?
- not being able to jump over the weird loopy things on the wooden platforms is annoying, you just bang your head on the skybox.
- the banks of the water areas are unrealistic, there isn't even a lip on the land - the water and grass line up exactly which looks unrealistic and weird. Try and put some of the muddy bank texture in, and angle them? Also, I had some trouble climbing out of the water nearest the bases, looking towards the base. <- we had this on Zen, no idea what caused it and it doesn't happen always.
- seeing as some people found it hard to navigate, you could do worse than use the arrow sign texture on the walls (which are pretty bare) to indicate directions to the bases, perhaps.
