The biggest suggestion I would make is to add some audio to give it some context. I thought the motion itself was nice and smooth but I couldn't tell if it was laughing, screaming demonic curses, or what. I liked the texturing a lot. I also would have liked some background or environmental context, but it may also be that I'm 'looking for a story' while you're primarily experimenting with technique. In other words, I may be looking for more than you intended. ;-)

Before they made me they broke the mold!
