I dont like it..
It sped up in places it shouldn't have, it slowed up in places it shouldn't have, wrong notes.. Sorry, but work on a better piano sound.
Kind of a waste of FL studio. Honetly, all you have here is a single melody and nothing else to compliment it. I know two year olds that could plunk this out on a keyboard better than this.
All I'm saying is reach out a little. I listenned to some other music on your page, and you can do better than this. I think you should remake it, and try using the metronome feature in FL to keep good time. Also, listen carefully to the original tune, you were way off on a key there.
Anyway, not trying to be too harsh... just try putting some effort into it next time.
though it's a bit slow
Chords and Bass
Chords are a critical part to creating the atmosphere. Try dipping into the bass staff, too. I think that you might have a bad scale going, as well.
but you need a rythym to keep in time and be less staccato when playing
