Every photo I have seen is exceptional, but this is the one I am making a comment. The issue is, I do not really know why, so I cannot be precise with my compliment. I guess, I just like it.
I have spent time studying each person. Your photo gives an exceptional introduction to each. It makes me want learn the whole story. (And, I like your composition).
The composition captures a sense of isolation, or, maybe it is a feeling of exclusion, as you name it, Karl. It matches the eyes of both the woman and child. Stirring.
