Illidan Stormrage. And he's a pony ... again. I've tried it once already, but this time it turned out a lot better. Though it's not completely my accomplishment, I used a really awesome official Illidan Stormrage artwork as a reference for composition and overall technique, so most of the credit for that goes here [link]
. Even so I think I've learned a lot while working on that piece, for instance that I have no idea how to draw crystals.

Edit: Oh, wow, it got to be the title image of drawfriend on EQD, I don't know what to say. I was not prepared )
