Thats just GREAT!
To be honest, the pad you put in the background is like a mask to the little mistakes which only those who have musical hearing can notice (like me =P).
That still doesn't change the fact that you got a pretty damn nice piano skills, and that you came out with a minimal number of mistakes, even more to say that this piece is very hard to play with the left hand simultaniously. Just happened to know that most of the records nowadays are recorded twice with different hands. GJ and keep it up!
