Pretty nice and smooth
A relaxing and well done frame by frame animation.
The detail put into each frame seems great, and personally I'd struggle to have the patience to do something (for a specific example, I'm looking at the waves near the beginning of the piece).
Whilst I like it and it is very good, there are still a few issues with it. The length is decent, but sometimes small segments seem a little jerky or rushed. Furthermore, the song is a little soft and fuzzy... Despite that, it's not bad, and it sort of fits into the background as a song which isn't too obtrusive.
Simple tip though- end the song before the animation starts again. As is, the music is playing multiple times since it's running as I"m writing this review, and it's starting to overlap each other many times, ruining it ever so slightly. All you need is to put a keyframe at the end of your animation, select the song, and set it to "stop" instead of start, as I'm guessing you have it set to.
It was good though, looking forward to any future work of yours =)
