Your covers are really great, I can't believe I never listened to them before! I was in awe of how you make the piano look so easy lol. I'm still thinking about self-teaching myself the piano since I already play an instrument, but never got around to it =P
Also, do you think you could give "The world is all one!!" a try when you can? You don't have to do it right away, but I would be happy if you could cover it sometime.
