I think the red colours are fine.
Meta|Fox, that's because you comparing with original one. Anyway, added surprised eyes
Truth be told, i can hardly even remember the old one. I'm trying to look at it from more of a natural standpoint. if the flip is a defence mechanism then the creature would have to be scared in order to put it up.
My only crit now is that the flip transformation happens too slowly, increase framerate for that part maybe?
