Like the song & the garagey style...I think your vocals are stepping all over the rest of the mix. Try & get rid of anything below about 100hz on the vocal track & that will take some of the "weight" out of it without really losing anything but unwanted mud. In fact its good practice to get rid of any frequencies that will be inaudible in the final mix, because if you leave them in they will adversly effect how the overall compression reacts since compressors usually compress the loudest elements of the mix the most, even if you can't hear them consciously...I hope this makes sense!
