You're aware that you took the easy way out
So I guess there's no point in re-iterating that. I think the presentation was really good. The music fit the whole neo-mystic feel, the animation was solid and it was good overall. Needs a little anatomy work on some parts.
But you really didn't have to sell out like that and use other people's characters, no offense, but that's not testing your potential as a creator, it's just an easy way out. Requires no character molding and gets attention with hardly any work, plus familiarity points. Maybe you'll get the hint eventually, your stuff's good, but that really took it down a notch because with those stolen characters, I know nothing about you (I should be able to in your characters), and there's no piece of your soul in them.
