Pretty cool rock band I produced - need some ears

Sounds good! Here's a couple of things that came to mind:

1) The synth bass is just a tiny bit in the way of the vocals. Dropping it like half a decibel and nudging it very slightly to either side might open it up.
2) The distorted rhythm guitars in the choruses have a pretty weird midrange, and they kinda clog the whole mix when they kick in. When they drop out, the song instantly opens again.

Anyway, good job!
