Rather than going into meanings with this, I prefer having people make their own meanings. I have heard them all, and some are partially correct and some are way off. But with art, its what it means to you.
This painting and title have many meanings to me, some good, some bad. It's huge (50? x 70?) and took me over a year to complete it, working on it here and there when I felt inspired. When I finished it, just on time for an art show, I knew it was complete.
