Personally as a photo, I like number two, but, and a slight but at that, is that his footwear lets the shot down and it could be a tad to the left of the frame. I know you cant change his shoes, but it helps to learn about the bigger picture I think.
With number one, maybe get the camera on a tripod with a timer and get some movement going behind him, DJ'ing is all about movement imo. Maybe people milling about, if only two moving across at angles, a slow shutter will create multiple subjects and get the deck spinning. I did some stock work for a DJ and we set up in the busiest street in Bristol at 1/10th or slower, locked the focal point on him and let everyone walk around us.
