This is Queen Admaria as drawn by Keetah. Admaria looks extremely striking in her black 'evil outfit' (e.g. https://www.weasyl.com/~tapewolf/submissions/1192055/admaria-the-black-queen-collab or https://www.weasyl.com/~tapewolf/submissions/1532076/queen-admaria-by-eliana-asato ) which is why there's so much art of her dressed like that.
However, this has led some people to assume that she's a tyrant, so I figured it was time to commission her in her default outfit so you can see what she's like 99% of the time.
As mentioned, this was drawn by Keetah Spacecat:. Her original can be found on FA here: http://www.furaffinity.net/view/24733373/
