Great job on Reign In Madness! Don't kill yourself over the lack of solos, though. I see so many videos where people are all about the solos and play them almost note-for-note, but doing so is quite boring. It lacks creativity and expression, which is what solos are supposed to be about. The rhythm parts are far more important anyway, since without them you simply don't have a song.
That Domination video is quite insane. I wish I had that guy's ability to hit those runs so dead-on; I've always had trouble rolling my hand on those ascending runs. It just seems so unnatural to roll my fingers in that direction for some reason.
