RRRROCKET Familiar
This one looks like the robots in Tarboy. I really like how you drawed it's legs, makes a feel that it has been made by a human or it was a human some time ago.
I am not overrating here - this picture has enough detail and story, while still being minimalistic. Always love that "Doodle art" which I never can make myself.
P.S. As always looking on characters with open mouths, I have the feeling it says : "Baa!"
