I once met a great photographer who among other things said that great photographer can make a worthy picture even in the middle of empty parking lot as long as there are some light there. To demonstrate his point he made out of focus and blurry picture of me and my wife. It was his signature style after all :) Here is my empty parking lot type of picture. I am far from great so I added 10 minutes of photoshop to this photograph of painted dot on asphalt.
You see something, you photograph it. You never know how it can be used later.
My kids are split between calling it a pie or moon.
