Took this picture of my son a few weeks back. I am not sure about the crop, I could crop it in many different ways
but centered like this worked best for me.
The photo captures a very natural scene well.
The only suggestion I’d make about cropping is that the marks on the slide are a bit distracting and you could loose half of the slide from right to left. This would also accentuate the length of the photo and the vertical dimension of of his climb!
Good photo.
