Until the drums started, I'm not sure if the guitar playing/timing was spot on, maybe it was OK (playing to a metronome or a drum part you mute later could be helpful). After the drums start, you're playing seemed fairly tight. I like most of the riffs, some notes/chords sounded kind of odd to me. But, if you like'em all, who am I to say? It's good you double-tracked the distorted rhythm guitar (they're slightly muddy, but OK). Keep at it! Please review my music at this link:
