This is a good, calm, pleasing composition. But for the shadow on the right. The photoreceptors of the retina vary from the center to the peripheral edge. Basically, cones at the center to rods at the edge. Those at the edge, coupled with the brain, are very sensitive to motion, and tend to draw attention away from the center. Unless the photographer wants this effect - increasing tension - edges are best kept neutral or framed. -Tao of Photography
Thanks Phil. I always appreciate your remarks. I think even now the double chevrons from the bench seat and its shadow pulled at me and forced me into the soft tree shadows. I wish the other dark shadows under the table were less but no avoiding them. It was a moment in time.
Your photo, sans tree shadow, presents a good example of one of the most primitive compositional elements - the corner to corner diagonal - in this case lower left to upper right. The left side is soft & warmer, while the right side is bright & angular. The essential balance of the Yin & Yang. -Tao of Photography
