There's certainly a lot going on here. I like the vocal sound and the way the instrumentation builds throughout up to the "quiet" bridge. My problem with the drums is the performance during the chorus sections; I wouldn't track the vocal rhythm that way, rather, I'd set it off.
I thought the bottom end was good as is. In fact -- and although it's hard to tell from the speakers I heard it through -- I thought that perhaps there was a little too much low-mids at times, ie a little muddy, at the points where everything was going on at once.
Lyrically, I thought that some of the verses were awkward, in that it's a smooth melodic type of piece but the words are not in the meter established by the song. Also, I like the central metaphor, but isn't it walking through the mines (as in tip toeing through a minefield)?
