The Rad Robot is the shape theme robot with color, a different pose, and penned in lines. I was using low quality pens I found lying around and am mostly used to using mechanical pencils for the line work, so there is room for improvement. The rib wires now have "Y" shaped wires near the top that go around the arm instead of just under it like last time. It was a sudden modification when I realized the shoulder pads were raised out of the way of that area, leaving it exposed.
