One of the most fun parts of animating for me is pushing the poses on anim layers, beyond what I had initially imagined would look good. Iteration is key! #animtip
I spent a couple of weeks thinking of a way to animate water for these shots. I came up with drawing the outlines of the water then fill them with Fractal Noise, then use Displacement Map to create something like refraction.
Drawing them all is also an option, but I'm lazy.
