yep. To get the size right make you lioness face left. Then grab the bar and pull it up. She shouldnt be too far from the top. Theres a tree in the character creation screen. If her size hits the branches of the tree behind her you should be the right size. If only FH had the numbers of the size sets like it did in IT so i would be able to give you a better size number.
OFFTOPIC: did you know that jinx and raven are voiced by the same person?
