I wouldnt hard pan the vocals like that, but I guess you're doing it for effect in selected parts...but it is weird you have it on one part and not any others.
Vocals seem a bit loud, under-compressed and too dry for the style. Guitars are kind of spongy sounding and lack dynamics/punch in the tone. Some of the stop/start parts are sloppy as well. The bass sound is very tinny (i guess that's the word) and it competes with the guitars too much imo. The snare seems a bit dry too, especially on the slower parts, and there's not much power to it to begin with.
