Leona's progress is much faster than I predicted, though I haven't finished the expression morphs which is easily the most tedious part of the modding process. So maybe I spoke too soon. At least other tedious part that is the hair is done, sure it has more layers to split and arrange than Karin but the whole process is more straight-forward.
I've even managed to port the dog tag and earrings, as I think they're essential to Leona's image. KoF trivia: Leona's earrings are actually mini-explosives she can throw at her enemies.
