Okay I was to lazy to take screenshots but I have a couple things:
1. The texture on the bunkers is a big contrast to the map and doesn't go well with the the textures. Maybe something like a ub_cliff looking bunker would be better.
2. The ladder to get up top just looks funky to me. I'm not sure if it's the texture or the size but if that's the only way you could get it I can ignore that.
3. Just a minor problem. Sometimes you spawn with a pgp. You may want to fix that for pub.
