I agree, the upper body of even a 'cartoony' nature will exaggerate the inverted triangle, but your getting there. I would strongly recommend you doing your own take on Superman directly from an anatomy book instead of images the various other incarnations of Supperman. It is great for a second model and please don't think I am trying to discourage you. I really like the head- has that 'THe Tick' feel to it in the lower jaw.
