Nearly movie quality character animations.
Since this is obviously about the animation itself (though the story was kinda cute, if not completely arbitrary), I think that the animations were very well done in that it was fluid for Aquanna (no pun intended) and Sparker's movements were faster and more abrupt. However a few of the close up shots seemed a bit off, though I loved how you could tell their exact emotions from their eyes.
Leaving the sound and story out of thought, the animation quality deserves a 9, but with those simple backgrounds I'll give it an 8.
Nearly movie quality character animation if you ask me. Some promising animators that's for sure.
