The lovely illustrator LL Tisdel has been offering character sketches for authors over on the WriteOnCon forums. You can check out the thread here if you want to try to get a sketch of your own character, and I'd encourage you to check out LL's gorgeous illustrations on her website.
Below is the drawing she did for me of Sirith- the main character in The Goblins' Price. She said she loves that Sirith has to rescue the prince, not the other way around; that's one of my favorite aspects of the story, too. :) Oh, and the background is Sirith in the wintry goblin pass. Too cool!
