On the scaling issue: I am doing a series of side-by-side images of Antonia and pictures of real people on a plane at Z=0.0.
I find for the examples I used so far, mainly standing poses, that I had to reduce the length of the shin to get a matching pose. Out-of-the-box her knees seem a bit far up her legs.

The reference poses I used are not stock, so I can not show them here. Sorry about that. Will search some suitable stock material to illustrate my point.
Leg length/body length ratio of course varies from person to person in the first place, and above that it depends on ethnicity and age. What ethnicity and age Antonia represents I do not know, but for the comparison I used typical West-European females of say 20-30 years.

This is in no way intended as criticism. The leg aspect length ratio issue accounted for, I think Antonia is the figure giving me the best and most natural results I have had.
