I would have shot this in portrait aspect instead of the landscape, I use a simple rule when photographing people, if there is just 1 person in my picture and the background is not suppose to be part of the picture (which in this case it isn't) I turn the camera sideways and shot in a portrait aspect.
This will give a much less cluttered background to the photo.
As for the subjects, they need to get some joy into there lives.. Smiles are good!!
