...well a NICE map, indeed but in my opinion not a FRONTPAGE map.
The idea of the map structure is a bit too simple for that and the lava theme's orange makes me wanna cry. One map of that is already overdoze but bearable but I don't really need many others. Sorry :-/ but that's just my opinion.
Technically the map seems pretty ok, but I think I maybe should save you a little embarrassment: you might really want to reconsider your clipping in the room with the cross-top (the one that's in the screenie as well). You can rocketjump the walls and do funny stuff you don't really want to see people doing in the next release... ;-)
