Im strugglin my self finding ways to make Palps in ROTS a bit more Original.
The conclusions were that his hood are too wide and he has some very fat neck.
Cheating in some motion shots and creating an impact to the more static ones palps have some potential to become more like he was originaly be....: A thin old lady.
(dont mind the background i left it with no special treatment)
Maybe... when palps changing his voice all the time before it will remain the same some small transforms on his face will explain why later in the movie is thinner or (place a better idea here)
