I like the texture and appearance of the part that is in focus, but the depth of field should be much better for a scene like this. It also seems cropped too closely, especially at the top.
I think either more or less of the far end of the see-saw should have been included. Just cropping off a tad looks like it was a mistake... whether it was intentional or not.
B&W is a great choice for this shot. Well-weathered equipment. I think I'd like it if I could see more of the great texture on the see-saw. I don't think you needed to get the whole see-saw in the picture to give the idea, so maybe a closer up view.
