If I was doing Knights Panther, then I would give a metal look to regular knight, blue paint to Inner Circle.
However, if one unit only, I might mix up the painting to represent different knights with different preferences.
And your painting on those two, makes me want to get back to painting my units ... Golden Lions are table top ready, Knight's of the Aver River are probably 80% done, and need to start my Knights of the Black Bear.
