Interesting...

U have the rythm and I think u do know how to make urself some good music.
The only thing u have to learn, if u do not know already, is about musical scales...
If im not wrong, I can hear in this song that the notes are a bit randomly placed and not following one unique musical scale.

I think if u learn them and follow them, u can make some good music :P

Its easier if u learn how to play piano too, if u do not know how to already :)
