The one on the right looks more natural to me.. mostly cause of the arm length, the other little changes are fine but were not the major things and well within human averages.  It's the larger head that makes her look younger..  perhaps a defualt just a tiny bit smaller..  like try dialing the neck length to 80% or 85% and the Head size to .025 instead, might be enough to get rid of the pinhead appearance without throwing off the appearance of her age so much.

Just my opinion, feel free to ignore me.  =)  Overall new proportions = better.
