Some quick work on an OC. Ostensibly she's a Draenei from Warcraft; in reality she's a half-demon PC from a different setting. I enjoy my Draenei Pally in WoW so much that I made my PC look very similar. The armour is original design, or at least as original as can be managed, given that I've seen and forgotten more armour than I can think of. It's probably only original in how badly rendered it is.
It should go without saying, but No. You cannot use this for your own purposes, and you especially cannot use her emblem. It isn't the most unique in the world, but it's mine.
