I FOUND IT!

Hey friends! After much searching I finally remembered the artist I wanted to recommend checking out. His name is Tony DiTerlizzi and he's illustrated many children's books, most famous being probably the Spiderwick Chronicles series of books that inspired a movie released by Nickelodeon. His website address is http://www.diterlizzi.com/. Check it out. I really enjoy his process and composition. He has strong artwork and has quite a bit on the internet to check out, although most of it is in flash so you'll have to be able to play flash. I hope all's going well with the monster designs. Keep up the great work.
