London Coastal Path
The path itself and the hedgerows are seen in part here.
The cliffs seem to be represented both with the rocks seen on the ground at the right, almost half way up the photo, and with rocks, mostly out of the frame at left, attached to a building's wall.
Or maybe the Pembrokeshire Coastal Path was just imprinted in our minds after 60 miles and dozens of hours on it and this was a simple abstract work of landscape art.
Anyway...note the pigeon exiting in a "northwesterly" direction.
