Hello there, from your same group of the NGUAC competition.
I like the development and overall composition. Your use of the piano is spot on my opinion, but it could make use a little bit of small arpegios at times.
That said, it is overshadowed a little bit by the mixing. The bass is way too loud at times, and i overshadows the other instruments. Also the water sounds feel a little bit out of place.
I also feel that some of the electronic sounds to accompany the overall harmony are spot on, while others feel a little bit generic.
Good luck ;)
