Denbigh,
I hope you don't mind me going further with Mark on his reading of your picture. That's one of his big interests, so I want to pick his brain.
Those who can't stand obsessional analysis of picture composition, skip this or be miffed!
Mark,
You're so correct about the arrow, but in the lower quadrant, the white space does help to provide our brains with territory in which to rebuild the remaining portion of the shadow, while the mass of the bench balances any exit down there. OTOH, your arrow remark still is a dominant force that overwhelms us.
Remember, Mark, in defending appropriation and arguing that the very act of taking the work is also part of the understanding or ethos of the price. So, could it be that Denbigh's composition with "the drive of that arrow out of the frame" could also be an esthetic worthy of our respect? This is just a question I'm posing not an assertion. I'd love to know your opinion.
