Good song, bad situation. Guitar work and mixing was fantastic, but rly man, bring your voice up! If you're worried about the tin-can effect (well done btw), maybe dull the treble down, gate the high pitch or something.
Sound better than Bobby Dylan, so inch your voice volume up a lil bit. Used to work w/ a guy who used to re-remaster hip-hop and rap, biggest pet peeve was: killing his hearing while trying bring instruments and/or vocals up properly. Last I heard he was going into the drapery business.
