Not bad.
I liked your characters, they were well drawn, and the mouth movements were fairly decent.
However, I think you should do a bit more work on the actual movement/animation of say...walking...swinging a saber...crawling etc.
It looked quite good, and the humour was definitely there, the voices were either too muffled or too loud for it, perhaps balancing the sound more would make it easier to listen to.
Also, I thought Anakin sounded like 'Wimp Lo' from Kung Pow: Enter the Fist. Funny. :)
Well sorry, just trying to give some friendly criticism. Well done with this, I hope to see a longer scene soon.
Keep 'em coming Joe.
Thanks.
