The volume and production is pretty good on this, but I felt that the initial build dropping out at 1:14 into yet another minute-long build was a bit deflating. Plus, when that second build finally drops into the lead, the riff is cool, but it could do with a harmony/flourishes/transitions.
I dig the automation build from 3:07, but, again, the constant looping of that one riff wears a little thin.
