Antonia does indeed have rather long legs by default. I think she'd make a fine runner or runway model. For a more average figure, it's a good idea to reduce the y-scale a bit on the thighs and shins.

I think the average ratio of torso to leg length is probably somewhere in the middle between Antonia and virtual amy_aimei, but maybe a bit closer to the latter.

Generally speaking, I seem to recall that adult women tend to have shorter legs in relation to their body height than adult men or teenage girls.
