It looks better now, but i do think he looks oddly proportioned if this were ment to be realistic, it seems more anime styled. You should really make up your mind on the style though, on the face i can see how the jawline, the eye sockets/brow and the shape of the mouth (spreading up to his cheeks) all look quite realisticly styled, yet the pointed nose with no nostrils and the body's proportions make it anime-ish. I'd also like to point out the absence of his ribcage =\

Oh and i did take into account the head under the hat -_-, if u'd noticed i scaled it so the face of the reference have the chin and the brow in line, technically that should be enough to have the drawing and model on the same scale. Andrew loomis is renowend for his knowledge of anatomy, if anybody really wants to improve their work (3d or 2d) i'd really recomend studying anatomy (start with loomis books online). For the last 3 years or so, i've been slowly working on my anatomy knowledge, however studying anatomy isnt something you can really ever complete, its far too vast and i'll probably keep learning it for the rest of my life.
