Your animation is exelent, the music is ok, but i couldnt se where the movie was going. If there was no text, it would be impossible to know whats going on. Thats why i suggest mabye adding a few scenes with action, fights or whatever, just so that the viewer can get a feel for your movie.
That 'sin' they want to destroy. You didnt get that idea from FFX did you? If you didnt then fair enough. But if you did then i suggest changing it, making your movie more original
