Gif Making - Booties and Mike Wazowski blink

Animated in after effects, I was set a challenge to do three gifs, and at the moment I'm re-capping after effects animation with a Domestika course. These are the first tests I did with briefs from the course.

The course is 'vectorial animation frame by frame style with after effects' by Pablo Cuello.

For the second eye I followed this tutorial here, I hadn't needed to use a mask for my Mike Wazowski eye, so I thought I'd to another to recap masking.
