Well some call the photos creative and nuanced. To me the exposure is different from shot to shot. The lighting is horrible, and in a few shots you can't even see the athlete's eyes, which to me is a big no-no.

He defends himself by saying he was unprepared, and he thought he would have had an area set up for him in which to shoot. I think he was the only one to show up with shoddy gear.
For a comparison we have Syl Arena who specializes in flash photography, who has done some portraits of coal miners. Personally the last one is my favourite. And these are GOOD.
