Not bad at all, dude. Better than I would have done. I actually like the tune change-up! I think you just sound too nervous. Maybe you were trying to not be too loud or something, but it just sounds like you're restricting yourself too much.

I will say, though, that some of the notes seem a bit too high for you. Overall, though, it takes guts to record something and to post it online, so good for you!
