Continued to work on the model. Consulted a bunch of tutorials and the Live2D documentation to get more systematic knowledge of how to set up a model properly as before I have only relied on intuition and the only partially translated Live2D official documentation. I now have a better understanding of what I'm doing, although I'm not sure this model I'm making now would work in eg. FaceRig out of the box. I'd probably have to modify it, but since that isn't the primary purpose of this project and all animations will be my custom ones anyway that doesn't matter much. I have now animated everything on the face, and I'll finish animating the entire head before stopping for today.

The model's parts are completed and the base colours, now I have to add details!
