Wow, your animation has really come a long way. It looks a lot smoother than it used to. I think you still need to work on your sets, though, as they don't look very convincing. While I appreciate the ambitiousness of the underwater shots, it might have worked better to at least chroma out the background and add a matte of the sea than have the blue baseplates.
