Erm...
sound, music and voice acting is terriffic. Story is very interesting and original.
But there's one thing that is quite obvious to me: About 50% of the characters in your movie have not been drawn by yourself. Look at the dancer chick for example or the necromancer when he was a student: Those are examples of excellent manga-style drawings. Then look at the necromancer when he's older or at Lady Medusa... those are examples of acceptable drawings. And if it was all yours, it would be consistently good or bad. The styles differ a lot from one character to another.
Of course using other people's stuff is okay, but you shouldn't take credit for it because that's just lame!
Also, don't be ashamed to do all characters yourself. Your style may not be perfect, but at least it's your own.
