That was pretty amazing
I know how hard fbf is, and man you did a great job of keeping them proportioned well! The art and animation was very well done, and although it sounded like you forgot to add sound in some spots, the sound was pretty good.
But I have a complaint or two...while I haven't watched Sonic X completely, I don't think there is an official character named Nazo in teh Sonic universe. If there really was, we'd see an official pic of him all over the place.
Second, while sonic and DBZ are simliar in a few ways, you made this waaaaaaaaaay too much like DBZ, which for me, caused the movie to stray from what makes Sonic its own cool series. Not only did you use too many sound effects from DBZ, but you made them fuse?! Come on...that's pushing it.
But despite all of my complaints you still have a good flash movie here. So keep up the good work! *does thumbs up* :)
