Robots! One hell of a subject, covers a lot of different bases. I think I can spend years studying this and still learn new things. The same basic principles of functionality, large shapes broken up in panels to suggest detail, and general construction stay constant, but aside from that no two robots (should) look the same. Every artist has their own approach, I'm just trying to find mine. A few months ago, the idea of drawing a robot was just unpleasant, but now they're very entertaining. Solving the design problem of how to take the overall large shapes and make them look functional is a great exercise. About 15 minutes on each of these, most of that time was spent just thinking "how should that leg joint function" "how will the head look" "how will the arm work?" etc.
