Finally got it to work. Good idea. Here are a few things that I thought could be changed:
Lighting - too dark to see at all in a few places
Grass mazes - one of the spawn points is almost impossible to get out of
Marking - there are several instances where teleporters or push pads are indistinguishable from the surrounding area (push pad and teleporter on a floor textured exactly the same as the rest if the floor, etc). Knowing where they are upon entering a room would improve gameplay IMO.
Overall, I would say that the map is decent. I like the sniper room in the "dragon". Seems to me that you have the potential to become a great mapper. Keep up the good work. Finish this one off. Then move on to the next one.
