Here's a classic male pose with an 'I' shaped line. Simply, follow the line from his head to his waist, another line from shoulder to shoulder, and one more line from hip to hip. Also, strong lines and angles help to add to the masculine feel of this image. Thanks to Daniel for taking time out of his busy schedule to help me out.

The setup for the silhouette was rather simple. On either side of the model there is a roll board used to block light from hitting the subject while at the same time bouncing light back onto the wall behind him. Behind each board there are 2 750 watt hot lights setup in 45 degree copy light fashion against the back wall. Also, the subject is on a raised platform covered in black to bring him further up into the light. Then, simply expose for white value of the wall and it's silhouette time.
