Straighten your back Picture

I like drawing men stripped to the waist, but I have some problems with male anatomy (where do you place the nipples, for instance? Women are so much easier). In this drawing of Hades I think I got the most of it right, though. But on the other hand, skinny guys are not as difficult to draw as muscular ones.
