I admit that I don't even know either. I will admit that this is a really good picture. I especially love how long it is. You really get the emphasis down well. I guess it's just some disturbing picture. I thought maybe it would be some reversing picture.
It's like when I see pictures of presents that open up people. People don't, however, puke birds. Well, maybe they do with some of the meat. The chicks look so monstrous. I'm glad the people aren't that well detailed.
