Where to start...
I would say that until you get this looking better.. you should not continue the series.. there i said it nicely.. also.. you should seriously think about actually :animating: the characters, not just constantly tweening of morphing everything.. and it would be great if the action sped up, the storyline revised, the characters were more interesting, the music was better fit, and charactes had moving mouths, or just voices even. just use a handful of these, and animate then remake this one.. then go from there... sorry, but i doubt this will make it through
