For me this is an example of a photograph which is sooooooo nearly a belter, but just misses it!

If the swinging conker was more in frame and showing a bit more motion it'd be class.

Doesn't quite make it for me. The motion is implied and not explicit.

This is good, but it could have been great. A little more of the swinging Horse Chestnut with some motion blur is what it needs. It's a great reinterpretation of the executive desk steel ball clicker toy.
