Again, nice update! I really like the "big" hero. As I said before, the face looks great. One thing I noticed, if possible, maybe add some definition to around the clavicle? This may create more "depth" between the chest and neck area. I can't wait to see them finsihed, and textured. Besides being protoypes, will you be using them in any projects? After this, you'll have to add a female, too!
