Wow, I've worked on a lot of canceled projects. But they reap a bounty of unseen material to post at this site. Here's another character from a movie pitch which I thought was pretty cool. I previously posted a couple of robots from the same project. At first glance you might think this guy a villain, and you'd be correct. I liked playing with the metal work like it was fashioned by crafts-monsters in a feeble attempt to dress themselves up. 
Here's a second take on the robot character and true to form, I'm often more partial to the first impulse. Though I don't mind this painting and I'm happy with the colors and shapes, I prefer the guy in the last post. This one has more of a C3PO vibe and feels a bit more predictable as the put-upon service-bot in my opinion. 
Here is a character design for an animated feature pitch. I found a stack of designs from this project and will post them over the next few days. I tried to be aware of the very broad volumes for this guy and as robots go he's one of my favorite that I've done.
