The vocals are pretty cool, like the reverb a lot. The rhythm guitar seems a little bit too mono for my taste, but I think you got just one guitar track. There isn't pretty much anything that is using the whole stereo image, which makes the mix kinda narrow. Even the drums seem to be kind of mono. I often use a chorus to "clone" the guitar to the other side of the panorama. So real guitar left, chorus (100% wet) right. Not hard left and right though. Maybe be it could work I your mix. balance is very good. Is it a live recording?
