The vocals just scream "And Out Come the Wolves..." era Rancid.
I mean that in a good way, hopefully you don't mind that comparison.
Definitely bring them up.
The whole "guitars panned hard left and right" thing works great for certain circumstances, such as very tight doubles of distorted rhythms, where both sides are playing the very same riff, very tightly in time so it sounds almost like one "wide" guitar.
Everything Metallica (and almost any other metal band) has done has this sound. One wide rhythm guitar (actually two or more recordings of the same lick "hard panned" left and right) - and leads in the middle.
On the other hand you have a lot of different lines on the right and left, and I know you don't want them to drown eachother out or muddy up, but the whole sound will be more cohesive if you pull them in, not necessarily centered, but closer.
The guitar tones in this song are perfect for the song IMO. The drums don't sound shabby either but you could probably pull up the kick and snare some.
Everything could be improved by playing a little tighter, and making sure you tune the guitars before each take.
Otherwise nice job for the first mix.
My one criticism of the song itself is that I'd like to hear a lot more of the cool vocals crammed into the three minutes of song, maybe find something to sing during the instrumental breaks and stick it in there.
