I wanted to do some studies on torsos, specifically pecs, as they seem to be very different between men, but anatomy books kinda tend to generalize everything to an athletic archetype, and because modern pictures are very embelished, I trawled the Vintage Sports Pictures tumblr. Krita, took me 2 to 3 hours. Missed a bit in the center due to my hardrive being full :)

First set is from a Navy Wrestling Club.

The boxer is Muhammed Ali.

And the final set is from a group picture of a Scuba Diving Team.
