David, this is a very interesting collection of shadows, with the fence and the arch. I’m having mixed feelings about the bright bit along the left edge.
I find this image fascinating and intriguing, but I have the same thoughts as @Mark_Seaver about the bright vertical. I spend way too much time looking at it and trying to figure it out, yet the for me the whole image is the great shadow lines.
Add a third vote for removing the window sill, David. I’d also get rid of the slightly visible gray stuff in the lower left. The shadows themselves have great mood and stand alone very well.
