Thanks for the comments. I see that I cut off the hand, which I regret, but that was a spur of the moment shot that I tried to capture and missed, and didn't notice until you mentioned it. I also regret some of the framing issues of the subjects, but I figured it was the best for the situation given there would either be something in the background that would distract the eyes, either people, man-made objects, etc. Some of these were shot through glass, so that didn't much help either. As far as the color, I guess I am not sure what exactly you mean. They look fine to me. I use capture NX2 to process the raw files, using a combination of white/black points and tweaking in WB from there. They all pretty much look like they did when I was walking through the exhibits, perhaps you could explain what is off about them.
