Sorry, but I think the colors in the image on the far right looks best, actually. But then, I am watching this on a PC with different gamma than a television.
There is one thing that bugs me, though: It is illogical for Luke's airspeeder to be in the left in the picture, when he is clearly running after the AT-AT. The airspeeder should be on the right in the shot, if at all.
In the images on the left, there is still a boulder left from the 2004 image that I think stands out.
