Okay, first, great job on the map. Very well done for your second map. I only have two things to say about this one, and I included screenshots.

First, fix this. When you jump up here, you hit the clip. There are only three cube selections, try to make it about 5 or 6.

Second, noclip the trimming on the stairs. I changed the texture to gold to make it easier to see.

Gonna give it a 6/10. I like it.

RaZgRiZ: Comments only accept html/php tags, there is no BB-code.

there are more clipping fails than the one zoocata mentioned .. work on that ,it's a good map 6/10
