Oh wow, this is great! You definitely have some skills with the piano, and the arrangement is really good. You managed to take a relatively short, repetitive song, and make it dynamic enough to fill 4 1/2 minutes without losing the interest of the listener. That takes real talent. I especially like the intro (don't listen to Lanky Kong, the intro was the best part for me). Hope to see you posting more of your piano stuff in the future, you really know your way around the ivories.
My only tiny bit of criticism is that the left hand is maybe a tad overpowering sometimes, but that could very well be the microphone/recording device as I've had the same issue several times. Overall, this was really good and a pleasure to listen to. Nice job!
