You really, really need voice actors. Seriously. And while I understand this is your story, you really misrepresent a lot of the characters. But that seems common in sprite movies.
The graphics weren't too bad, and I was glad to see some Seiken Densetsu 3 in here, but... only Duran? Where's my Hawkeye?
You do a good job of picking the music, although it was odd that Frog's theme was playing while he wasn't around. And that Dactyl's flying was kind of embarassing to watch.
