The grain and pinhole fuzziness, and the ground-level perspective all give a sense of a tennis court gone to seed, unloved, unused, brought home even more by the empty chair. Having a ball in the foreground rather than the leaf would completely change that impression.
very nice, I think I prefer the leaf shard (as is) to a proposed tennis ball. You could have lowered the ISO and played a few sets with yourself. Sort of a ghost match. Or maybe just a blurred foot. I like the empty chair.
