I feel you. But that's the problem inherent with creating a new color scheme.

I think quite a few people have mentioned the yellow skin tones and sepia-like tendencies at points. I feel like that could be enough for a shot at some different settings.

You_Too went back and forth with many different setting before people agreed it was looking correct. I think to get it closer to perfect some adjustments might be made.

That is in no way meaning I dont appreciate your work or am trying to give you a hard time. I just feel strongly about the colors and especially think using the Senator images for the overall tone is not a good choice. For years I have looked at pictures of original Star Wars props taken by people at exhibits and the colors differ hugely from one camera to another.
