I am not experienced at critiquing photographs, so be warned.
Given that the focus of the photograph is the bench, I would like to see the entire bench. With its one leg partially cut off, I think of a photograph of a person with her fingers cut off. It jumps out at me.
Perhaps get a bit lower when taking the shot--almost as though you were a child experiencing the wonder of the fall.
You might wish to frame your shot so that the one set of tree branches on the close side of sidewalk are out of the frame.
And last, the sky is blown out or completely gray. If there was some color and texture, that would be better.
All that said, if I stop looking at the photograph technically and just look at it for pure enjoyment, I like it. I like the peaceful serene setting with beautiful colors. I love colors, so that alone makes me like your photograph. I like that the bench is strong and prominent.
I hope these comments are helpful.
