Speed drawings are almost always fun to watch. I feel it might fare even better on YouTube. As far as the video and the art work, I feel some music'd help make this video more fun. Feel free to browse NG's audio portal for some great royalty free music. Feel free to use my music ;)

I think the character's color scheme's overly-simplistic, but those are my tastes. I feel an X-Men vibe, like Storm and Mystique. Great effort, thanks for sharing. Put some music in though it'll make this more enjoyable to watch!
