Yarr.
This map was posted only 2 days after I went for a vacation trip through Europe without any chance of playing it before coming home...
Having finally played it, I can only again say what the others have already said - what a nice map. Nice environment, well-planned monster encounters, and even the sound was used well (I play with the standard Quake soundtrack).
Here's my first run demos:

There are 3 demos in there because I started a new one after the skill selection, and DirectQ bugged out once somewhere in the middle so I had to restart from a save game which unfortunately messes up the monster/secret count, but it was something like 10 missing monsters and maybe 5-6 missing secrets. Easy skill.
