@ButtWorldsMan @Tfmonkey I will comment, that not all of the "age factors" necessarily apply. If you remove some of blend them in combinations, they can be effective in communicating greater or lesser age. Unfortunately, no mention is made of the head-to-body ratio.
Additionally, there are further considerations such as the selction of clothing and specific types of outfits. If she's going to cook fatty meat, she needs an apron to not get burned...
