(CA9-4) 1.5th part base animation (Patreon)

And here goes the base for the 1.5th part. It still misses base for a cumming part, but this will be added eventually. I still need to refine a new workflow but it seems like it's already a lot more efficient than the old one. At least, it feels like a solid way to animate. I'll later make a post explaining the new workflow in detail, maybe it'll be useful for someone.
