Great work
Very nicely done, the fighting was fun to watch and the animation was very smooth. The characters could use a little more detail to them but then again everyone has their own way of drawing. Try to make the girl more feminine rather than making her more masculine. The voice cast could use a bit of work, you can get voice actors by posting demands in the NG Forums. The character who uses his bones as weapons was a very creative idea, and I have to say the outcome kept me in some suspense.
In your author's comment for the movie, you might want to add facts like how long the movie is, how many frames, how long it took you and the ups and downs. I don't know about other users but I often wonder about those questions when I watch a flash animation.
