The photographer of this piece most likely did not find these beautiful leaves just arranged here by chance, but rather found and collect them and put them there for this reason. Obviously it would be too perfect if the trees just happened to drop these leaves in one spot, but in the end, the photo looks very attractive to the eye. You can steal this idea too and just make a collage of the coolest looking leaves you see. Take advantage of the changing of the colors of the leaves and this season. Don't be afraid to experiment and explore.
