My variations on Diabelli's Allegretto in C

Hi,

I am studying piano and there's this cute Grade 1 piece I am practicing now, Allegretto in C by Anton Diabelli. I thought it would be interesting to change it, and this is the result. I never studied composition so I don't know if this is any good but I had some good fun with it!

The recording is a MIDI played by my notation software, because I am not good enough to play this smoothly myself yet.
