I'll add some constructive criticisms: Playing-wise, 0:32 sounds a bit sloppy, as does the transition at 0:38. The heavy riff after isn't as tight as it could be. Mix-wise, it sounds a little flat, like it needs to be more stereo. And it's probably my new headphones that I'm not entirely used to, but it sounds a little bass-heavy and thick for my tastes. Though that's really a personal thing. Aside from that, it sounds great.
