Hybaj: Thanks and yes it needs more tweaking to get more accurate, the reflective properties and hightlights are not quite there yet, it feels to dull to me. As you suggested i will also add a more greenish tone to it. But this is a tough one to weight in properly, atleast for me because it can so easily and quickly turn into a fullblown copper or something else if you adjust the colors to much in one direction.
True that copper has as many different looks, almost an infinite amount of variations can be found of this material so it's difficult to recreate just one that fits all situations and needs.
I'll see how and if i can fix this, if not i hand it over to Kurt, he can easily sort this out.
