These are just some random figure study sketches of male anatomy. I didn't use any photos or live model for reference, just tried to put down some interesting and varied poses. I think some of them turned out pretty dynamic, and even realistic in a few cases. It's fun to go back to figure studies now and then (not to mention really important... I should do these more often, especially for men, who I draw far less often than women).
