This map looks really good. Just a few points of critique though:
I think you should move the spawnpoints closer to the spawn doors just to reduce the walking distance a bit.
The barriers above mid really obstruct jumping to an annoying degree, they just feel too low.
The stairs will be annoying for soldiers as rockets can go right through them.
The health pack in the back corner as you exit spawn to the right is kind of an awkward spot, it might be better in that grass patch next to the left fence or just along the right fence. (Though I should playtest first before I comment on this kind of thing)
Also shrugger found a way to escape the map but he wants me to keep it a secret so he can troll people with it.
