Oh shit!
I have no other words to describe this, there are so much genius ideas put together, out of the visual aspects, you brough a lot of new gameplay things. And I honestly like the layout a lot, the mapshot said it all...
Even if this is impressive, I think there are a lot of mapmodel and maybe you can reduce the number, 600+ is a lot and because the map is a galery, the engine must load a lot of them constantly. I don't know why I could not load the skymap, all the mapmodels and textures loaded well but the skymap did not.
I've found a bug and probably something you missed at the exact opposite (accordingly to the map overview) of the first bug:
I don't know if it was on purpose, but I found this too, a fence was placed in a way, another one in another way, and two fence spots are missing (missing fences are probably on purpose).
To finish, when I jumped on a small wall, I saw I could go trough something that could have been clipped, or at least the string, here:
Also, your mapping style fits more and more with one of my unfinished map, you should check it one day. :P
