Old but awesome! :D

Awesome indeed,;) this is a nice topic for a full length animation if you ask me.

Thanks, it's a good concept, originally I wanted to make an long animation but my pc died and i not could finish

I really enjoyed this, thank you for posting the link

Yeah this is pretty sweet. I'm not sure how long this has been or if you still animate like this, but you should consider cleaning up your brush strokes more. After you draw the frame just select click the figure/brush line with the selection tool (V) and at the bottom of the toolbar there is a curvy line that will smoothen the brush strokes out.
