First problem I had: to launch the map through the console because you didn't have a gamemode selected when you published the map.
The way to fix this is by selecting a gamemode in the check boxes. In your case it would be the classic game type
After running around your map for 10 minutes, I found a few things that are kind of over powered.
Awping on CT side A site is severely over powered, you have long routes that the Ts have to take, and the CTs will greatly benefit by buying long ranged weapons here. I thought of a solution but I don't really know how it would work out.
You should add a hallway here, so they don't have to deal with the mid awper directly unless they really want to
I thought the hallway would look something like this:
This door should really be opened faster, try changing the speed to 250 and see how it works. You can always turn it down if needed.
From CT to B, you have a random ledge, consider adding a railing (this is really low priority but just thought you should so something about it)
On B site, you have a small office type room. Consider adding a window here. CT's only have 1 main entrance to watch from.
Next to the overhang that the T's use for an entrance, you could add a 2 man boost here to catch oncoming T's by surprise
Thats all I have for now.
