This shot was very simple, although we attempted much more laborious ways of animating it at first. Instead of hand-drawing the wave pattern, in the first attempt, we landed on a single static wave asset and multiplied them, and staggered their position and speed so they appeared to move in perspective.
I used this first version of the Colorado color-key as my reference:
The choppy water was a first attempt:
The long gray wave pattern was what I ultimately used as the wave assets, and colored and animated it in After Effects:
And this is the final shot!
