Again pretty good, little sloppy but I'm being pretty picky then.

Anyway, in this particular there's no reason to downpick everything, and it almost seems like you can't altpick properly. The beginning riff is usually altpicked, yet you downpick it... Very good downpicking speed though, props for that.

Thanks. Actually, I used to play the intro alt picked but after a while, I started playing it downpicked just because I felt like playing it that way, since I feared that I would get out of touch with downpicking.
