Drawing on Life

What you see below is not a photograph; it's one of Kevin Okafor's astonishingly realistic graphite drawings.  As an artist who works in graphite and charcoal myself, it has never been my desire to be so painstakingly representational.  To me, that's the province of photography.  

The larger question that's been raised about Okafor's work is whether it's 'art.'  

I'm interested in your thoughts.
