This is a simple repaint useing the common metal colors. I did what most do and hand painted the figure flat black. Drybrushed with silver and a silver/gunmetal mix on the tank treds. I took a good look at him in the movie he does have a goldish huge to him. So in order to replicate this by mixing silver with gold and lightly drybrushed all over minly focusing on the torso area to get champagne effect. It is not meant to stand out but rather have a subtle look. You may notice in the pics. Finally I painted smaller details in regular gold. Enjoy
