Mine was made by my girlfriend, Ralkarin (of the Shadowalkers), who also made (and/or helped make) quite a few of Our other icons. Ralkarin's pose page can be found here (http://shadowalkers.silentshadows.net/ralkarin/poses.html).

Kay's was drawn by Ithica (someone We know on a chat site We frequent) as part of a commission for an outline-only pose, and then it was colored and shaded by Ralkarin for Us. I don't think Ithica is taking commissions currently though. :/

Hope this helps :)
