Great map,

a nice and creative map.

just a few things i would do diffrent( maybe you would consider them helpful):

-first i'm one of those people who do not like corridor spawns that much, so i would give both
sides a second way to the stonehenge section and an additional entrance to the lower part.
This way players are able to have early game choice, best example is dust_2.

-the t spawn exit should also be more visible, i only saw it once the bot's ran that way.

-speaking of bot's, maybe try regenerating the bot mesh. they seemed to be really confused.

-the upper spot is really great, but for the lower one you should make it more dominant or just
mark it with a bombspot spraytag.

Thats all for now, if i find mor i'll let you know.

Waht i really liked is the lower area, maybe it's a bit empty at the moment, but still it fits well and with a bit more editing it could be perfect.

Cheers
Incomp
