All this being said, the Lenka character you have been using is lovely, except for the size issue. Can't you just scale her down another 5% or so?

Aislinn looks believeable as a teen to me. There seem to be makeup options that are either very subtle or totally natural and look quite young. A very versatile character, and I like that she doesn't look too obviously like V4. I don't know about the height though, you may have to scale.

This has been fun, I love looking at character options. Please show us a render of your final choice.
