The main difficulty is getting the face attractive but unique. Getting the balance right and having someone that is attractive without being a barbie doll. Having built an anatomically accurate male body ages ago, it should be a hell of a lot easier as she'll have much smoother forms and I won't need every little muscle to be quite as defined in the topology but still, I can't spend anywhere near as long on this one. Another challenge is being distracted whilst looking for reference lol. Gio
