I agree with Monroville and another commenter that Luke's face is too orange in that shot. The bluer tint to his face gives one the impression that Luke is so cold that all the blood has drained from his face to keep his core internal organs warm. It makes him look in far more physical distress than having a face flush with warm color.
Somewhere in the middle between the bluray and Ady's preview shot seems more right to me. Just my opinion, of course.
