While the result of this 2nd exercise was not as visually striking as I had hoped it would be, putting it together taught me a good deal. The entire piece was composed in Cinema 4D. I created a pretty basic Xpresso controller to help manage the scaling animation, but all of the smaller assets were keyframed.
I think I need to improve on emphasizing the smaller assets, but I gained a lot of creative insight making this composition. Most notably I now comprehend how the Range Mapper node works.
