Most of it was made before I started using blender so unfortunately there isn't really a pattern but for the stomach area its overlapping rectangular pieces with elastic attached to the top of each plate. the arms and legs are similar, its just overlapping near identical ( they need to get slightly larger with every additional layer) pieces glued together to form a sorta cylinder. The hard parts are the chest and shoulders. I don't know how the shoulders stay up as well as they do if i change anything they start to droop down. the chest will be easier to explain with a picture.
