Sketch of the Day: More Robots

I'm still working on the style of robot to go with my story. 

I want something that is both a throwback to the 50's idea of robotics, but with a "softer" sense of edges. Something cute, but also metal. 

This is a sketch from when the robot, who previously had been the only robot and/or human consciousness on the planet, finds out there is another just like him.
