Quite decent Piano, but...
I think an organic stringed Bass (I'm thinking on a Bass Guitar) would have gone a mile further than the synthetic one you pulled. Percussion could use some more improving, adding a little more groove to it. Maybe some break beats when ending those 4/4 sequences, the snare doesnt seem to alive, maybe a kick could make a nice difference.
My 6 because of the piano, which was enjoyable to listen, reverbed, and EQed in some way thanks to the reverbing. Keep trying. Improve those percussions...
