This headshot was done by the very talented  SINister-Panthera!!!

You should go check her out for yourself. She is currently open for commissions, and is offering them for a very reasonable price.

Also if you go check out her journal ( http://www.furaffinity.net/journal/1574378/ ) you to could have your very own free headshot from her. Art talks and, as you can see, it has nothing but good things to say about Sin.
