Awesome job youme. Rated it an A-.
Pros: Very nice detail work. Great layout. You are the cliff displacement master. Your lighting is spot on and your brush work is near perfect.
Cons: Really the only issue is size. Thats where the - came from. The .bsp is 92 mb uncompressed. You are going to be hard pressed to get impatient users to wait that long to dload. I have about every custom map out there, and yours is by far the largest. The only one that comes close is cp_vertigo at 61 mb (This probably explains why I can never find this awesome map on a server). A comparable map to yours, cp_castle3 comes in at only 41mb. I know it is probably too late in the game for you to do anything about this, so you will likely have to get the word out that people need to download your map from here first in rared form and not off server.
Suggestions:
This is area behind Red first spawn room. You should add a fence so they don't walk straight into the skybox textured brush.
If possible, instead of the no entrance texture at startup have the fence parts attached but hanging and then at setup they fall down.
Bugs found:
This is the hallway to the left when you come out of the Red spawn in the third round.
This is how ceiling should look.
This is how it looks at certain angles. Goes black.
Sorry for the long post, but I think a picture is worth a thousand words when giving map feedback. Bottom line, awesome job and keep up the very great work.
