Ah Unoa heads and faces are much smaller than standard MSDs like the ones from Volks. Generally next to other MSDs they can look pin headed. Their head circumference is 16.5cm (6.5inches) vs 18.5 (7.3inches) MnF head (older sculpts) or volks which are almost 8 inches around. I know all this because I'm trying to figure out some sculpts to fit my 6 androids. Two or three will be unoa sculpts, with one MnF Kyle and one Dollmore Judith. That's what I've figured out so far but it might change in the future if they Unoa's don't look right with the others or vice versa.
