Being an audio producer is like being a painter. You have your paints and a whole blank canvas in front of you. Your job is to fill up as much of that canvas as possible with a pretty picture. I'd say you got the pretty picture part, the song was very clean and nicely mixed. But you filled up like... only a third of the canvas? Perhaps less. In the frequency spectrum of 20Hz to 20KHz you had lots of holes which just made the song sound "empty." That's the only and biggest error with this piece.
