There are rare occasions when we have a male model and he actually has muscles. This was one such time and this pose with a broomstick over his shoulder like some kind of weapon was so much like the kind of thing I want to draw that I got in a big hurry to finish it. As a result I drew this figure kind of sloppily and too large for the paper. So I slowed down, got out a fresh sheet of paper and started over. Now I have two completely different renditions of the same pose, both of which I worked on later at home. Looking at things like muscle charts and body builder photos I exaggerated his muscles before creating a costume etc.
So this is the same drawing as above, but I shortened his legs so he's no so freakishly tall and using anatomy books I detailed his muscles. This is actually reasonably close to what the model really looked like. In the second version I beefed him up a bit more.
