I've spent a long time on this one today. This character is Allyri Hail, the Centaur Rogue! I rolled up this character for a future game of Dungeons and Dragons 3.5 with some friends. She is quirky enough that I just had to draw her! There is also a NSFW version of this picture that can be found HERE or HERE!
Coincidentally her color scheme is based on the two sets of D&D dice I own (Light Purple with White and Translucent Teal with White - Both from Chessex).
