Character Art for the Film
And yes, I am aware that Pixar did a monster with blue fur as well. The similarity ends there, I assure you.
Threw a quick test together on the weekend to see how the hand-painted environments might look with the 3D treatment. The top image is the original colour key, and below it is the 3D set. The painting gets 'projected' right into the 3D scene, and the result is the ability to move the camera around the painting in actual 3D space. The quicktime video is just a simple camera move to demonstrate the effect.
