Hows this mix?

at :20 the guitars go mono for the riff and it sounds really odd. Other than that, drums need to come up a bit.

That section you mentioned only has the one guitar playing.
But i forgot i automated the panning on that section to the center. Cant get the panning on that bit right. Anything else i need to do other than raise the drums a little.
 
I'd say either automate the volume down a few dB in that part or just leave the guitar panned to one side, OR have both hard panned guitars play the same riff to keep the stereo field open. Sounds bad with it panned center, IMO.
 
Still sounds pumpy. Im only on tiny laptop speakers right now though. Drums seem a bit better but I think your compression on the drums may be the culprit.
