I wonder what picture the sculptor was using when he designed this?
Sculptors have little to do with the final product; they get tasked with an assignment and do it to that extent. Andy, and based on past comments, probably another sculptor or 2, were assigned to produce a Princess Leia in ANH sculpt. I'm certain they have no clue what paint apps are or aren't going to be done on the sculpt, otherwise it probably would have some aspects to the face sculpted for looking out the corners of the eyes more in line with how that looked in the film when she did it for the memorable shot. Sideshow and LFL are ultimately who makes the call on how the painted, tailored production piece will look.
