I feel that the emotions of Ash weren't properly portrayed in this Flash movie. As Pikachu was being devoured, I simply wasn't feeling the sadness that I should have. I feel that is an issue on your part, you simply skipped over the grieving and weeping.
I also feel that the animation could have used a bit of work; it was too amateurish for me to feel the "theme" of this piece.
I'm sorry, but your work gets a zero for the above reasons.
