I rented Disney's Pixar Wall-E and enjoyed it very much. It's true, that it has a darker feel than the usual perkiness of Finding Nemo and Toy Story. The emotion of Wall-E is wonderfully captured. I liked the part where they were in the garbage bin area and "mice" were crawling around the trash. Not the real mice mind you the kind you use to navigate your computer. A great message about dealing with the trash on earth. If you haven't seen it go and rent it and see for yourself!
I drew this sketch in 5B pencil and then added the darker lines and shading with woodless graphite 8B. Wall-E's body is out of porportation but other than that I thought it was a good sketch.
