This is a lovely photo and you indeed have a beautiful message. Every person has a different perspective on things and many a times the message the artist wants to convey gets completely lost as the audience tends to interpret it in their own way. For me this is an image of sorrow, the crack window somehow remind me of war and fear. The light outside showing that everything is finally over. It makes me feel an eerie silence that is felt post war.
Whatever our interpretation, it is amazing that a picture can bring out so much emotion in both the person capturing it and seeing it.
