Steve,
You did a terrific job on this.
The backing tracks are well mixed. Nice balance between guitar/bass/drums.
It reminded me of early Green Day. A very appropriate vehicle for the lyric. The genre makes the too-low-to-sing-vocal "work".
Cool ending.
(For a track like this - heavy instruments - you can run the instrument mix through a good pitch shifter and bring it up a note or two in order to do a vocal when it's just a bit too low to sing to. Just a thought if you run into this in the future).
Enjoyed that!
