I don't know about editions, or what not, but in my book, the only characters that were illustrated were the Cullens, and then, when I got to the other covens, their memebers weren't. 
 I liked how some of the Cullens were drawn differently from the movies, except Bella and Edward, and I loved the image of Renesmee(though she is going to hate herself when she grows up, whether about her actual name or her nickname, I don't know, but it if were me, I'd hate myself for both. Yay Jacob and Bella). Anyway, the Denali, the Volturi, the Egyptian coven, none of their members was illustrated, I mean, why do we need the book for other than to see the characters?
