Nice build up at the intro.
Very dark, the way to presented the vocals. Nice, deep, ...really like the vocal and guitar blend at 1:59. That is a trick I want to learn.
Then at 2:40, when you let loose on the vocals, rip it!!!. The piano droning away just underneath everything else, mixed well.
To me, the vocals are the best part, because considering who you made this with, everything else would be expected to be clean, tight, and tasty.
