This is a nice list, I'm all for it. I think that some of these suggestions probably overlap with suggestions earlier about the whiskey to champagne tones for whiskers and eyes. (which are kind of like cream to brown.) And we GOT COGNAC! Thankyouthankyou.
I think some of them were: champagne, brandy, whiskey.
I am particularly interested in your Rust Oxidated eyes since they could be really pretty 2 tone eyes.
