As listed under the credits, I did not draw the reference picture used as a base for this skin. Although I used to draw a long time ago, I have yet to decide if I'll start doing it for public display purposes. If I do, I'll certainly consider your request if you happen to still be interested. In the meantime, I have made a skin for each of the Mane Six which you can see on my submissions tab on my profile. Here's a link to Twilight's skin http://www.planetminecraft.com/skin/humanized-twilight/, hope you like it!
