The filesize is pretty darn huge for how little stuff is in it.
The latest classes version is 5.76 mb. This is 11.
Dat extra music. Rozark made a good decision in saying he will post it separately. I'll be glad to compress it if you'd like.
I think I'd like Ice Cap more if you cut off the top part though.
Actually, instead of flat out destroying hard work, I believe it would be better if the map was a single piece. Of course, joining both parts might make it big. I say it could be a good idea to meld the outside with the inside in one way or another, although I don't really have a problem with the map as it is right now. Of course, that doesn't mean there might not be problems.
Perhaps less of the same textures?
I don't believe this map is a texture soup, and even that is not the bigger problem here, as I explained above. Speaking of texture soups, FMP01.
3rd map:
This map is way to BIG, gosh if this was played in duel everyone would say BAWLISK. The skybox's texture offsets are off, but doesn't really matter to me if you fix it; I just thought I'd point it out to you. I liked the concept but way too GIANT.
Unless it's a Duel map pack, people shouldn't make maps centered around duels only. Also, the Skybox did matter enough that you reported it, and that's great. Still, you're the one to complain about huge maps when you don't even listen to advice yourself. I don't have a problem with people doing that, except it sounds hypocritical coming from you, especially when I tried to help, and there's no way it doesn't bother me. So sorry if it comes off as flaming, but it's the naked truth.
