Some thoughts - only thoughts...

OK... the Vader Head reveal... in "Building Empire" we see that he is supposed to be breathing off a ventilator as the helmet comes down. This is not too clear, and should be (kinda) easy to stick in, maybe even using a still? Makes it seem like Vader is more helpless without the armor.
Also, the back of Vader's head looks mighty good for a person who got burned that badly, and it does not match up with ROTJ. What do you think about adding a little extra nastiness to his noggin to make it look more forbidding. I mean, I remember thinking the scar was cool, but since ep6 and ep3, I think that if they got his skin that smooth, the scar should have been a cakewalk for Poppa V's plastic surgeon. And I know people who got skin grafts and they are not that smooth.
