I think he is using the model from looking at the video.
i also find my brothers statement to be true. I'm a huge Sora fan, and I think that maybe for the psa, whenever sora hits someone or something, you should make stars come out (like in the real game).

oh yea, and the walking looks a little awkward.
Its a good idea but that should be done wayyy later.
But you know what i really like from E.Y's Sora PSA? That you can do a combo with him in the air with Forward+A that hits 3 times, and it connects really well too.
Maybe you can try implementing that in one of his moves?
