Pros: awesome mapping skill
Cons: still, small runways/ uncool hostage placement..
Improvements: told you before ;D
Notes: n1 as always !!!! I want MORE !!!

The CT spawn has only that vehicle blocking the way to the right. There is invisible wall in front and backside of it.

The map looks nice but thats about it. Too many details showing up at same time and the playable area is too open. It kills the fps and since this is ment for multiplayer, fps really goes down on an actual server. This sort of explains why you included only 16 spawns per side. However, i have told every mapper that adds less than 64 to add total of 64 spawns, since larger servers than 32 will sometimes want to use these maps. I know many, many, many maps that have only 32 spawns and they are either edited with entspy or edited in hammer to include 64 total spawns so everyone can fit in.

However, one of your T-Spawns is not working. Type in map_showspawnpoints into game console to see which. You also have some console errors about solid VPHYSICS which can be fixed by either making the prop not solid or to use bounding box. There is also error about displacement. You used a displacement texture on normal brush which is not made as a displacement. You can fix this by making it displacement or changing the texture.

Also player bumping into an invisible wall, a clip or player clip brush is sort of annyoung. Why dont you add some fences there or some other props. That Zombie there with the headhugger doesnt fit the scheme either.

Overall, its nice looking but won't be a good selection for more than 10 players. Fps goes way too low. Be brave, change the map structure to break visibility.
