The thing about the Great Mother is that the symbol her form is closest to-and seems to have been taken from-is a small stone sculpture, not a huge clay mass. While it's understandable that primitive people could have created such a form in that image and then worshipped it, there is no such creation remaining. In order to do the Great Mother justice, I think you'd have to put yourself into the place of a very ancient people, not too different from those who lived on Easter Island, for instance. They created their own god out of an enormous amount of soft clay and then worshipped it. It's a pretty alien frame of mind, but I think they would have gone to a great deal of loving care and artistry, and would have continued to add to and evolve the "finished" product, decorating and enhancing it. Speaking of which, I think she should heal afflictions-after all, if she loses a part, all you need to do to fix it is add more clay.
