Eric, Thank You! This is a good gift. 'Spurred discussion w/ the Mrs. 'Sorta on the fence w/ this one, but I think I've tried to use just form & pattern before where the anchor would have completed compositions I wound up abandoning.
Here, a crow/bird lower left would work, even a large fallen maple leaf. Unless tiny, a dog would seem to serve in the upper left where the horizontal brickwork meets the walkway at the left edge. It gives me lots of mental fuel for working the composition that leans abstract. Thank You so much!
I don't think you need the end of the run in the lower right - there are clues in other parts of the image. As it is it is a dominant image element, while I think the curves tell the story.
The left side could also be brought in a bit to keep the subject all brick.
This is not going to be an easy picture to live with - the right to left apparent slope of the bricks and the curves are going to be in tension. Not that that is necessarily a bad thing!
Without people, it is not clear how the space is supposed to be used - ramps, seating - which is good.
