I am SO using this for my troll beastlord.
My eyes nearly popped out of my head when I saw this. I would be very interested in a version without the buttons. I don't think a Done button is even necessary. I just press ESC when I'm done with my spellbook. I liked your other skins too but a background with bears on it didn't seem right for a troll, so I'll be holding out for something like that. Again..WoW
