WIP Still don't know who probably Zone-tan (Pixiv Fanbox)

Here's a WIP of my animation so far. These are thumbnails sort of. Rough sketch of one of the main movement of my animation. I want to make like a struggling, pinned down, paizuri thingie since I wanted to animate breast physics. The red line is one of many roughs of the boobs moving as a unit that I have to plan out. I think once we get to the paizuri bit, there would be a lot less movement. Only this struggling phase would have such snappy wide movements.
