Wow, looking great.  It is hard to judge without knowing the context and hearing any sound.

One thing that bothered me was near the beginning the water has oily globs or artifacts that move distractingly.

The second thing that could be done better is when the camera goes under and out of the water.  Maybe if there was a better transition or a splash it would be more appealing.

The third thing is the clouds could be more realistic.

Thanks for sharing.  Was the render time long?  What version of vue was this animation made in?
