The looping wave motion is more difficult to create than I expected.
Two of the earlier mistakes include a standing wave and a “smoke” that moves up and down.

After watching a candle fire extinguished by wind, I tried to capture the essence the memory via drawing the simplest possible animation.
Without looping, it is easier to create a jumpy fire followed by a rising and distinguishing smoke.

I drew two circles by my left and right hands with onion skinning over multiple frames, and observed the circular animation caused by unsteady hand motions.

A spider on a flower

A spider, resting on a lamp shade, scurried away after being gently poked by me to see if it was still alive.

This exercise aimed to reproduce my impression of its movement, but over a flower as captured by an earlier photograph of another spider instead of the lamp shade.

I drew the flower and the spider in multiple layers via Fresco, exported the pdf file to Illustrator to animate the spider via puppet warp, and assembled the final video from the individual spider layers/frames along with the flower.

Even with puppet warp, the authoring process still involved tedious manual repetitions, which can be alleviated by autocomplete.

Custom puppet exercise

I created the vector graphics in Ai Draw, export to Pr for layer editing (Ai should also do but looks like my Draw app sends the .ai file to the Ai program on my company computer while I was at home), and import to Ch for facial tracking and performance.
The mouth tracking and animation need some investigation.
