Overall I think it was a great cover. A few things kinda stuck out at me though the first is that I think one of you should have played that riff at :45. The second thing is that at about 1:50 when you're tapping and your friend isn't, he probably should have played the little chugging bit before starting his tapping. And then lastly is that you're friends guitar is a bit squeaky during his tapping, that's not a big deal though and is just a bit of a tone problem I guess.
