Hi, you have some inspiration in there, "living" or "musical" notes mate. But something was strange to me, and it is the start, it is like the initial note of the melody is missing from second 0:00 to 0:06, the melody enters a bit late in my opinion, I would start the melody from the tonic chord (first one).
Are you thinking in extending it?, it could be nice to hear it with development of the melody, as it is a good melody and chord selection (at least the ones I like and I would use). Also, I would vary the chords a bit using lower notes of the same chord (as inversions), as the chord progression is repeated without modifications,. which is not necessarily bad, but this is what I would do.
Just my point of view, of course, I do not own the truth here.
What piano library did you use?, it sounds good.
Rgds,
