No frame at all, actually. Started with the torso, then did arms and legs. No real underlying skeleton in the usual sense, but most of the armour(minus the two front bits on the head, the toes, and the caps on the tanks) can be removed without structural compromisation.

Inspired by too much Transformers Animated, except more cluttered/greebly.
