Very neat piece of music - the use of key changes were very lovely.
My only critique is that I wish there was a little more work with the dynamics. You do have changes in the overall volume, but I think I would've liked to have heard a little more done with the intensity of the notes being played. That way the sections that are meant to sound softer/quieter or louder/with more intensity are actually played accordingly.
Thanks for sharing your work :)
