I think it's instinctive, sometimes you can take one look at something and just decide you don't like it or that it doesn't work for you at all. I think this picture has that effect on some people. That's ok with me though, I'm just happy if something I've created makes someone have any reaction at all -good or bad. Indifference is the worst thing I think...
In real life I get really mixed comments about this one. Some people love it and some hate it.
