UGH!
That was really, really poor. I realize you didn't have much dialogue to work with, but you could have added something instead of stretching every line to the point of not wanting to hear it again! Graphically it wasn't great, but at least it wasn't sprite work. Audio-wise, the voiced were well recorded, but got annoying fast. The song was a midi, which doesn't have the words but still, you could have probably done better.
On a side note, you obviously have no idea how a guitar works as you do not play with your palm, and going down usually doesn't produce higher notes, and note that high would not be played that far down. No points docked for this, but it looks really goofy.
