Duane Hanson did some very competent representational sculptures. Here's a sample:
I don't care for his viewpoint on life. Think of him as a 3 dimensional Norman Rockwell who sees everyone as being beaten by life. At museums, they have problems because people keep trying to talk to the works. Polyvinyl castings with real hair and clothes. He died in 96. Very popular in Broward County, Florida, though, if you want to get an idea of his politics.
Personally, I think most of the good work is going on with computer artists today. Here's a piece my brother did.
He illustrated computer games for about ten years, but got tired of working 80 hour weeks, only to get laid off as soon as the game was completed. Check out photographers and computer artists working outside the mainstream and you'll find some very good work.
The janitor doesn't look too beat down to me, but I don't imagine Rockwell painting him that way.
Harder for me to see the skill in the shark, because I don't play with Photoshop-like programs. For all I know one could just scan a photo of and do minimal touch-up. Moving images that one can't just film and fool a little with - I can understand the skill there.
