Very cool stuff here, John - lots to like. The one thing that strikes me when the heavier crunch guitars play (0:43-1:15 or so), there's some fizz/highmid happening that could be lowered to make the guitars less harsh. Not the distortion, but the q of it. .02 for your consideration. Rock on. 

Thanks a lot for listening jshep - and for your comments.
I'll listen again to those guitar parts...
