I come back a week later, as promised, to post my progress.

The rig is mostly done! I rigged all the ears and tails too. I'd like to add some more advanced features to it, but the base is ready. I think next week I'll finish rigging the skins and/or start creating some basic animations!

Here's a wip gif that shows the current progress:

The face is not fully rigged yet, same for the feet. I also need to draw some closed eyes so the poor creatures can blink :D
Thanks for tuning in, and see you next week for more progress!
