I think this may in fact have been your best submission! While it didn't have color, it was still wonderful to watch! It was just great because you had no idea what was going to pop up next. It was also great how everything turned out to be important in the end. I also thought the ending was really sweet (in pretty much every sense of the word). I thought the headless guy looked like an arrow pointing up.
It's also great how you lead up to the next major holiday after this. For some reason, the artwork reminded me of "Rocky And Bullwinkle". It was great to see everyone and everything move in such an energetic manner. Any fan of animation should like this masterpiece. The overall positive attitude is great too. I hope you have a great Halloween too!
