Comments as I go:
I don't like T's spawning on the train track, gets people stuck in spawn for a bit too long
A place that allows you to jump out of the level: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=448646875
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=448660256 (player gets stuck in there)
Completely broken boost spot: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=448661919
Very large
Too many random corners and spots for people to hide in
I'm not even going to add anymore feedback in terms of what is wrong.

The map would very fun for something like TF2, CoD, Battlefield, or Unreal Tournament. This map does not feel like counterstrike at all, I do not say that to be mean, but to help you with future projects or to help you clean this up if you want it to be a better map.

This is really cool, Keep up the work
