One thing I love about being in animation is that it affords me the opportunity to research and learn about things which I would otherwise never encounter in my daily routine.....like tropical birds. Apparently, cockatoos shed a good bit of "waxy" dust - feather bits, dead cells, etc. The first test was to visualize that effect as well as to establish motion for falling feathers.
The second test, a festive confetti logo, was previs for a teaser.
