Jeez, I did say that I don't see much of a difference in some of them, didn't I ;-) I do clearly see the difference in the one you just posted and I do see that part where it gets darker (I did that to compensate for the blown out explosion but I might need to back up there), which is exactly one of those I meant when I said I was gonna try to fix some :-)
Also OMEN, I'm not sure if your monitor doesn't add a bit of a yellow tint, you seem to see yellow a lot, where I don't see it at all. From what I see, the wall in the picture of Leia and Vader Yoo_Too posted, the walls are slightly bluish white with a bit of purple in the darker areas and I don't see even a hint of yellow anywhere in the walls. The faces of the people there seem to be a sort of pinkish orange, which I think is exactly what a normal natural skin colour. Actually, I'm sitting in a café right now and when I look around, people's faces seem even more orange than those in that picture.
EDIT: And in your regraded version, the walls now have a bit of cyan tint in the highlights and the faces seem unnaturally pale.
