Been there, done that
So this is pretty much another 'ordinary kids gain mystical superpowers to fulfill an prophecy' kind of series, eh? This movie is like a crash course into nearly every youth-oriented anime show...you even managed to nail the archetypical collected-minded every hero, cute female, quiet 'n' cool badass, demure sage that provides the powers, and the hot evil chick.
That's just my gripe with unoriginality. It's your idea and I wont ask you to compromise it just to please me. But you probably want to pick up some books on the fundamentals of storyboarding for animation. Because if you want to establish a facial expression or a character, you're going to want to hold a close-up frame of them for more than a split second.
