Here's a little feedback on tings I noticed when running around on your map. Note that I just loaded it up on an empty server and didn't play any real matches on it.
First thing I noticed it that some of your stairs are very step. For example I wasn't sure first if this is adrop down or a stair when I left spawn. It's probably not that big of a deal, but the stair ratio seemed odd to me:
First of all I have to say that the clipping you've done so far is pretty great! Everything seems very smooth. There was just this one spot where you leave spawn, where you can get stuck. (Note: I enabled the coordinates on the screenshots so you know where I'am standing):
Align these textures on the wooden structures. Almost all off them seem to be not alligned:
It also seems pretty odd that blue and red seem to spray there logos on the brick. Make a wooden sign behind it to make it look like it has been put up there:
I only found one sigthline where I wasn't sure, if it was intentional. You can stand on this ladder next to spawn and look all the way onto the point:
Please fix that you can shoot directly into the spawn! Nobody likes dying a second after he got spawned:
The last thing I noticed is this ledge. What purpose does it have? All it does is mess up your aim when you're walking over it:
Remember I don't want to make down your map and just try to help you. I know that some of these points are very minor, but this is just because I couldn't find any majore problems.
Good luck developing!
