Hey Ady,
I was wondering: When Luke is training with Yoda on his back, when the shot with the line "You will know, when you're calm, at peace...passive." is up, could you give Yoda's left hand some 'articulation'?
(Frank Oz puppeteered his right hand and mouth, so the left was just sort of stuck there). It doesn't need to be big, just some grabbing-like motion so it doesn't seem so dead-ish. I know this can easily be achieved in After effects.
