It's a good start.

What it really needs is some good bass accompaniment that increases the mellowness of it and maybe something that will add a little more melody like a guitar or a flute. If not that, then maybe do a little more with the piano (that is if this isnt a sample).

Also the drums feel really stiff. Personally I like to have a lil swing to my drums so I don't quantize usually. Try experimenting with that. Oh and if you're going for a smooth feel I recommend have different snare with possibly a little bit of reverb.

But you do have a great start here. Good luck!
