She is super unstable with her base. One slight touch could cause her to fall on her back.

My solution for this is to provide a small base/item (stack of coin/acrylic base/layered paper) about 5mm~2 inches under her right foot.

This will help her foot contact with the ground and improve her stability massively.
Still, even with this, she still will fall to her back in case the impact is hard.
