here some color ideas i have.. my take is to make the armor inspired by spartan armor, going more in the golden and red color. also i add some dark grays to make some contrast to the gold to make the gold stand out more. also i make the skin dark blue to make it contrast to the bright color it has on the armor.. also i push the contrast here so we can emphasize the focal point of the character.. hope this helpfull | Artwod Feedback
