I liked the head on Starsock's edit most. The others seem too top-heavy, I think. It's hard to explain. Also, despite the style, you may want to add a tiny bit of shading to the body, because as it is, it's not conveying metal very well. If you take a look at robo9's sprite, it has a little extra shading (but not as much as the metal on the car, for example). You may want to add some. Just a thought.
