Pretty good so far!
I think this shows a lot of promise, honestly. I think you've got your artistic style down and have a good sense of what your figures are like in the round. I'd say at this point if you focus on your aesthetics and clean up the art a little bit (I understand a sketchy look is what you're going for, though) and learn a bit more about Flash (play buttons, replay buttons, links to websites, etc.) then you'd really have something here. Keep it up man.
