Maybe I am just nit-picking here because I know we can't really see much of the headsculpt! But he kinda looks a bit fat in the face, more like Revenge of the Sith than Return of the Jedi. Also the skin doesn't look grey scale enough.
I am hoping they pull this one off as I sold my DD Exclusive Version for this and that was a pretty decent figure with the two sculpts.
As for coloration, I'm pretty sure a fleshy tone is "canon" for Palpatine now and not the very pale white look from ROTJ, few products use anything but these days.
It's ROTJ with the throne, unless as far as heads and such, HT goes for a middle ground between 3 and 6, but knowing HT, I'm sure they'd save 3 for a full 3 figure with unique ROTS costume.
