Well, strictly based on pictures since I’ve never seen either in person, these are the things I personally like better on the new ESB sculpt over the old sculpt (as far as I know the ANH V1, V2, and R1 all use the same sculpt).
-The assymetrical cheeks are more accurate.
-The eyes are smaller and more accurate (sorry Lord Valefor, I don’t know what you see. They eyes look way too big on the old sculpt and look spot on on the new ESB sculpt, IMO)
-The neck is the proper length (no more giraffe neck Vader)
-The grating pattern behind the “teeth” is now correct
-The general shape of the dome, and its more leaned back position looks more accurate.
-This may not be universal and I don’t have time to dig up and post the pics right now, but when I compared a good closeup of the ESB helmet to a good closeup of the ANH V2, the details were so much sharper on the ESB. I was rather shocked at just how soft the ANH V2 sculpt was in comparison.
That being said, I think the R1 figure still looks GREAT. And it’s a real show stopper if you resposition the dome. If I could get either for retail, it’d be a tough choice as each figure hasn’t things I really like about it over the other.
But aside from the tusks, I DO think the ESB helmet looks like it might be the best yet. But the tusks really do have a huge impact on the look of the face and I really hope they can be fixed.
Oh, I also wanted to point out the side by side by side pic isn’t the best comparison since the ESB helmet is at a different angle (camera is lower) than the other two, so of course it doesn’t line up as well.
