I have absolutely no problem with fan-created content, so long as A.) it's not for monetary gain at my expense, B.) I am properly credited as the copyright holder, and C.) I get a chance to admire it. Beyond that, go nuts! Back when I first started Bardsworth, I used to get quite a bit of fan art, and it would always make my heart swell every time (cue the audience "Awwwwww..." track). I've sort of missed seeing peoples' takes on my characters.
