Finally decided on a pose I like, shes supposed to be drenched in water and of course the aftermath is Ranma and Ryoga turned into their secondary forms. There will be an empty bucket as a prop on the side. There are two leg positions as you can see. One she sits on the ground and another she will sit on an elevated surface, probably a bench or a rock. I have adjusted her proportions again, arms are thicker, head is smaller, and some other parts bigger ;). A couple of facial expressions I want to experiment with are surprised, angry, or annoyed. Other things on the to do is are of course clothes, add more asymmetry, gravity.
I may release her bust soon on thingiverse, stay tuned.
