I worked on a similar figure project (17cm, 10 limited copies, fully assembled and painted) as part of rewards for a Kickstarter. They were equivalent to 50€. Planned to reprint and sell them 80€ after the Kickstarter end.
Felt 80 was a good balance between affordability and profitability

The simple rig in itself

Forgot to update, but I did this animation inspired from Spirited Away's little heads (apparently called Kashira) after clearing the 3rd chapter of the course.
I'm not an animator but was pretty fun to make !
