Looks nice enough, but the clipping is awful. Since skytexture is already set to zero, you should take advantage of it and fix some of the more awkward places to clip on the map. I'd suggest you remove all the clip around the outsides of the map and just let players fall as they may(which seemed to be your original plan anyway)--Keep the death in the ledges around the outsides of the map though.
I'm going to hold off on voting for now...
Non-clip-related bugs:
-There is a hollow space behind the ledge off the side of the map under the quad.
-There is a hollow space under the staircase that leads to the underground tunnel.(by the bushes)
-There are two more hollow spaces next to the vertical tunnel/drop thing.
-Yet another hollow space(smallest gridsize) under the ladder in the pool.
-There is a tombstone-shaped piece of geometry outside the map.
-The corner of the map under the quad has a minor geometry hiccup.
-The railing below the quad is inconsistently textured on the front face.
-The Green and Yellow Armour should be swapped. As-is, the green will only be used by players that accidentally fall in the pool.
Clip-related Bugs:
-The clipping near the quad is missing-- allowing the player to fall off the map and get stranded off-map.
-The clip above the quad is broken too-- almost as if it were meant to compensate for the jumppad throwing the player too high in the air...
-The in the corners between the quad and the rockets(where the shells are), the water at the top of the steps should be clipped.
-In the corner w/ the rockets, there is a square of clip at the bottom of the stairs that was obviously a copy/paste error.
-The clip is broken all around the 6 pillars on the outside edge of the map-- Random clip between players that does nothing, broken clip over the top part and over the sides too.
-Behind the yellow armour, there is clip coming through the wall from the stairs behind it.
