Your photo has nice geometrical shapes to it. When I shoot certain images such as you have and it doesn't really fit into some conventional box, I like to playfully step outside of the box and flow down a path of abstract form. Here is what I did with your photo. I did it with Picasa2, it was fun and I only did this to share what I do with some of my photos before tossing them. Sometimes I create a form that I simply like. Then I keep it.
