Nice looks you have there. I like especially your bg work and those hills in water under the bridge.
Layout is classic styled, reminds a bit of ctf_Artep. Top route is mainly out of use, but I guess that's what you were heading at.
All in all nice map. You could try next to make something that isn't so classic, because it seems classic styled custom maps won't get popular, if that's one of your intentions. Flagthrow (ctf_IceBeam), reverse flag maps (ctf_Hormone), using crawl speed bug in ice (ctf_Coolbya), intensity (ctf_X) and etc are the things that could make your map fun & popular.
