if you are an old fart, don't eat any onions. you'll get tear gas.
OK, first off, cool tune! I hope you don't mind a little REM comparison, but you're more Pearl Jam in the vocal department. so that's a pretty nice hybrid!
Mix-wise, I'm not an expert, but I was listening on headphones. I'd take the jangly rhythm guitars on the left side, and lower their volume just a bit. Your main vocal is a little panned right? I might move toward center and increase volume - or perhaps the move itself might increase its perceived volume?
Bass guitar might be brought towards center as well? Was it panned a little left?
cool tune - did you "hpf" everything except the bass and kick? that might help eliminate any "mud"
I think this is a pretty good tune and a nice effort!
cheers,
