Nice scene, but it feels like the contrast is a bit off. There is a lot of middle gray without much on the black/white ends (with the exception of the person, the black/whites on him/her are so dramatic, it makes them look like a ghost!)
A very good line created with the wall. I like the way it leads to the boy but he seems somewhat far away and there is some detail lost in his face. Overall the photo is fairly grey, but the boy stands out well from that.
Wonderful pic - love the curve of the walkway, black and white to truly capture the feel of a rainy and quiet day, and for sure handsome little model you selected!!
