I suspect the first girl, vogueing overtly, is primarily an "outfit" study...I particularly like the 4 cute buttons on the shorts. The top right drawing is done with a 1940's pinup mindset. I'm assuming the 3rd sketch (botton left) was the inspiration for the 2 recently added photos on Jamesgirls of models hugging trees. As for the 4th, surely we all understand by now that Mike digs dancers warming up their big, lush legs.
