Nice, i love the sound of that last riff (i was actually learning the right-hand technique for it today, harder than it sounds to play it right)... the interlude at bars 33 to 36 and the drop into the riff worked really well too
Periphery, love that shit!

You've posted this before, and I believe I complimented the thing- if not, I definitely remember listening and enjoying. As is, I don't see any reason to separate the ideas, they work well together, it's just a matter of going back and forth between them properly, which you've done.

Not really enough done on it to constitute a full critique, that's all I've got.
