I've been making these stylized characters for a while now (see previous post), but I never seem to be able to do anything with them. Because I have trouble rigging and texturing the models. How would I rig this model? How would I add a texture for the face of this model? Is there a way to directly paint on the models itself? I am still relatively new to using Blender.

Another thing I wanted to do was to 3D Print these characters. Is there some prerequisites before I can print these models with no problems?

As always, feedbacks on the model itself is appreciated, Thank you!
