Here are some robot designs and sketches I did for Urban Threads recently. The top drawing was a little detailed and we decided on going for a more "chunky and blocky" look. The design is geared (pun intended) for kids so I think it was a good call.
I enjoy seeing into the process of some one's thoughts and love looking at artist's sketchbooks. It's sort of like the bonus footage on a DVD you enjoy. They show you behind the scenes of the film or commentary from the director about their thoughts, budget, location, etc. I love that stuff.
