Thanks cb, I will bear that in mind. I was trying to make the metallic a little less of a focus so it didn't draw away from the banner, but it sounds like I went too far. If I get time, I'll come back to this model and add some more depth to metal.
Welcome to the soul soul-destroyingly critical world of CMON. The banner has a nice combination of colours but you could improve the look of your metals by trying to increase the contrast, (darker recesses and brighter highlights). Bright silver on the very edges of gold makes it look more shiny for example. Hope that helps.
