Why is this so hard? A). Children have a different head size to body length ratio than adults. Poser has a head length guide that one can use. B). Children *do not* have a bust line. A bust develops during puberty - after which the 'child' is a child no more. I just checked and Aiko, by default, has a bust. Default Aiko is not (!!!!) a child despite her facial appearance. In fact, her facial appearance is irrelevant in her default state. An objective measure would be something like: --- If the head is less than X% of the body length (whatever is normal for children) **and** the bust is less than X% of the waist or hip size (for example something representative of an "A" cup) then it's a 'child.' Otherwise it's not. --- This will allow people to create small busted women or fairies. And you could could still go to a court, look the judge in the face and say, "Children don't have developed breasts like this figure. Nor are they biologically built with these proportions. Therefore it's medically not possible for this to be a child. It's a stylized bunch of pixels." For the record, pedophiles are interested in small, childlike chests and figures. A cute anime face with B cups and adult proportions is not what interests them. And I use B cups as an example to point out that you don't have to give a figure an abnormally large bust for this to be defensible.

Before they made me they broke the mold!
