Have you submitted this to get tested? I doesn't seem like it, and your map would greatly benefit from getting tested.
Also, you should add version numbers to the end of your filename. The servers bug out if you submit different files with the same name.
EDIT: I did download your map and run around it for a bit. Here's some quick feedback:
- There should really be more than one spawn exit. If there's only one, spawn camping becomes really easy.
- The flag is *way* too close to spawn. Maybe move it to it's own rooftop?
- Your map is really long and flat. Snipers are gonna have a field day with this, and fast/blast jumping classes are the only ones going to have fun going after the objective.
- The little walkways shouldn't be the only way to get over the deathpit. Look at other custom maps, like CTF_Convoy, for example. Sure, it has little walkways, but it also has multiple paths, not to mention jump pads.
