The look is quite original, not typical industrial and not typical Q3 techno style... strange athmosphere, the green fog looks nasty :) Unfortunately there is not a single ambient sound in the whole map, again...
One thing I don´t like is the escape teleporter in the flag room: by using this you are practically out of sight for the flag room defense AND you get a Meghealth, that´s a bit too easy for escaping flag carriers.
