I would compare the bendiness of Green Stuff to the bendiness of the material the hands of Megamis are made of. So when it's too thin it bends too much.
Now that I've tested further from what I've made so far the only problem I'm having is that the joint that connects the lower body to the upper body is too bendy. When I connect a heavier head (from toys, not plastic models, like Assault Lilies) it's too much weight and the upper body falls backwards. Pinning it might do the trick though. I do have a different epoxy available in my country that would work too, that shit cures like stone. I could try that too.
