Damn!
I could really sink my teeth into this track; all together its sounded great. The sections were well thought out and i could really dig the chordprogression, especially the key change about three minutes in!
I really only had to suggestions;
1.) The drums sounded a tad week. I'd recommend bringing up the bass frequencies for the clap and adding some 'oompf' to the kick. (slight distortion could help you with that)
2.) Around 2:22, just after the breakdown, I'd recommend crescendoing a bit more; building the sound before you go back to the chorus. It didn't necessarily sound abrupt; maybe adding a gated/ retriggered snare in would do the job.
All in all, a great track; I really appreciated this. Keep it up dude! -Peace
