making a composition

Believe it or not this painting began as my soccer/basketball field. You may seem some similarities. The idea came to me when I was on the field observing a nocturne. Darkness makes the important shapes come forward. Like a sculptor I gradually carved away at the landscape to create something pleasing. A reflective surface and distance weaving back were fabricated to make a composition with interesting values.
The focal point is in the bottom right point, according to the rule of thirds. The rule of thirds is a compositional tool which shows you the sweet spots. Each time the lines intersect there is a good place for your focal point.

 Here is a tiny drawing that shows my notan and compositional lines. The lines show where the movement happens in the painting.

Later, while reading Composition and Perspective I noticed the similarities in composition to Constable's famous The Cornfield.  Not that I am saying my small painting in anyway resembles the greatness of Constable..just that there are compositional similarities. I read that Constable regarded this painting as one for his best researched works. He made studies of every detail before building it into a satisfying composition. The parts did not appear in nature in the same positions as they do in the painting. He did what all painters do, he moved things.
So painters, feel the power! Just because you see it that way doesn't mean that you paint it that way.
