I had the pleasure of working on a book cover this year. The book is called Man's Best Friend (by LJ Stamm and RJ Evanovich) and has a pretty freakin' sweet storyline. Check it out at www.binaltro.com.
This is a colored version of the Kark I posted earlier. I really liked the description of this creature so I decided to do a fanart; lo and behold, it was used for the back cover!
