This was a fantastic, fun project! You never know when you will get a great shot of a person, a dog, or where. I did this whole job using only the clone brush tool. The wall was super easy and took no time at all. The bike wheel? It was pretty easy but time-consuming. The slowdown came from using textures between the spokes for a more natural outcome. Finally, rebuilding the wall to sidewalk transition wasn't that easy; I am happy with the results.
