The muscle anatomy is all wrong, his deltoid isnt a bone or bumping. its part of the shoulder, you got it right on the right side of his body do the same on his left arm. also his head is a bit skewed, as if you where tilting the paper while drawing. the clavical, neck and shoulder muscles should show a bi more and his shoulders should be 1 hear apart lol. sorry for the rant. learn anatomy. bend it to your will once you have lernt it but dont skip any steps. I suggest you learn anatomy and then bend it to your will. right now you have only a vaige understanding of it.
