Oh, I do love the simplicity of the context!
These photos really are about the boys only, nothing distracting to be seen, and the lines formed by the rows of seats (which I assume they are) add to the calmness of the photo - with the two boys NOT being calm at all, as a wonderful opposite!
Maybe, in order to also make the second in row as "quiet" (background or context-wise), crop it so that ceiling line no longer shows, for while it is well aligned along the front bench, that line is crooked, and I find that a bit distracting.
