I animate as a hobby, so I'm lacking in the technical training department. Hopefully I'll get the chance to fix that someday.
When I have a little more time, I'm going to add controls (play, pause, etc) and fix up the backgrounds in the end so the quality doesn't drop so drastically. If you have any suggestions beyond that, lemme know!
It is very beautiful and somewhat melancholic, but in that nice way in which it makes you feel better at the end.
The sound complements the visuals so well the two create the narrative which i love.
My suggestion is a minor one - i think some of the waves could blend into each other a bit smoother or, rather , emerge more smoothly; and then you mentioned you'd fox the background and transitions in the end so they flow smoothly, and think that's it
