Baby's got Back

You ever notice Iron Man's back? In the movies, the design of his armor gives his lower spine this vaguely inhuman curvature which is really slick. I couldn't find the perfect picture of this, but if you've seen the Iron Man movies a few times, you probably know what I'm talking about. Emphasizing this muscle development is not exactly common, mostly because characters are usually turned toward the viewer. It's also not common with male characters, because emphasizing an s-curve shape is much more typical with female characters (I'll probably get into that in another post). I think the reason it's done, though, is because 1) superhero type male characters are typically barrel-chested, and these muscles (the Latissimus Dorsi, according to my anatomy chart) are very important for that and 2) it gives the character a nice butt, which--let's be honest--makes viewers look.

My drawing was of the popular Green Lantern character Hal Jordan. He's turning to the side, but while I was drawing the picture, I thought of this.
