The map looks good. It's also very nice to see, that the barrels and lots of other stuff is aligned.
I bet that newer players can't grab the second flag. You should think about a more newbiefriendly way to get high there.
Also, 5 flags with 15 points (!) are definitely too much. Take 2 flags for each team (without a mid flag) or 1 flag for each team and the mid flag. Maybe use flags with less than 5 points, too.
All in all I don't like this map. It's mapped well, but the ice parts destroy the complete map. As others said, it's looks more like a jumpmap.
Add keys like "speed" "#", "accel" "#", "decel" "#", etc. to the func_plat to make it look much more realistic.
Now a few screenshots. Note that some pics need to be fixed for both bases.
You should avoid those overlapping brushes. Make the lights a little bit smaller.
In the red areas are clipbrushes necessary.
Move the textures a little bit.
Why? Just why?
I though it should be a matchmap and not a jumpmap!?
The red brush is a little bit too small.
You need to rotate the blue brushes (90°). All ladders are misaligned this way, so you need to fix it a few times.
A few of this ramps are aligned, other ones are not aligned. Just move the texture a little bit.
Hehe, you can see the plant through the wood. Move or rotate ("angle" "#") the func_models a little bit.
Green: Here should be a clipbrush, too.
Red: This texture doesn't fit, but it's hard to align in this place. I would really choose an other texture for the hill.
Green: Does the water area is necessary for the gameplay? I can't see the transparent brushes above the water, but I guess no, because you can't get in. If no is correct, I would delete the water for lower r_speeds.
Move the texture just a little bit higher.
Move this ramp, too. There are a few misaligned ramps, I didn't make a screenshot for each.
Brushtext looks ugly. Replace this horrible brushes with a nice own texture. Shouldn't be this one yellow, though?
Red: Wrong texture
Blue: Move this a little bit.
These wood things are misaligned and looking weird. I would really try to find a better texture for it.
Blue: Move this a little bit, too. I believe it's only in the yellow base.
Red: Rotate this texture (90°?). I guess you must also move the texture after the rotation.
Some faces have parts of the light, but they shouldn't.
