Robot Lord Round II

Here's another stab at the Robot Lord character design. I did a drawing somewhat like the one on the right and thought it was pretty funny, which gave me the idea that perhaps this character can extend his limbs so that he can be tall or short depending on his mood, inclination or what he needs to do. 

One challenge with this idea is how do I shape his torso and hips so that it can be lean like a hero or rounded and pudgy like a toddler? I might do a CG mock up to see if it would work. 

You can see I kept the cuboid head with the face circle. Not sure if his limbs should be more boxy to reflect his head shape. Perhaps I'll try that next.

But as usual, let me know what you think!
