Hey, cool dude. Amélie. Good movie, good song too. You should try to learn it on piano, it's fun to play.
You have got to fill in the emptiness though! Add a little reverb maybe, put some basslines in there, make a more progressing beat, add some echo effects, put in some sound effects, some crashes, etc. It's just sort of blaaaaand right now. Keep practicing-- haha I just listened to the end. That struck me as funny.
Oh, add pads, too. :)
But above all keep practicing!
