Good start
You have a start to a movie.... now finish it. Your drawing of the mage was very good and everything flowed together nicely. Although there wasn't much in this you did an okay job. You should make an entire movie mocking 8-bit by having your own drawings beating the crap out of the 8-bits. It would be very comical and original. Just animate A LOT more than what you did here and make the story A LOT longer. Good idea here, you just need to finish it. Good luck in your future movies.
