You only added him a armor, nothing else, and you removed the team color, how is it usable in any map?
the chainmail is decent, but could be better; reduce the black amount betwen each of them, having pure black or dark colors is to avoid.. you have a specially huge one on the shoulders. its a commonly repeated error on a lot of skins.
next time, do more than adding him an armor, give him a teamcolor if it's going to used more than 1 time in a map, and dont recolor again, especially if you're going to darken the skin.
