I had no idea someone made this great tool called RE2MV. It is amazing. I wish this was out years ago. Anyway, I was able to view and export Sherry Birkin's final and beta model.
You can see a big difference. The beta model has a bigger head, and a little huskier than the final model. I think the beta model was supposed to be 8 or 10 yrs old compared to the final, which is a 12 year old girl
And Yes, I know I put a g at the end of Birkin in the thread title, my mistake
