Very interesting composition. I can't really tell if this is relevant to the theme as you can't see the face of the subject. Although you are given some hints with the cane, but that in itself doesn't say that the person is "old". Great shot but the relevance is an unknown.

Nice image! Interestingly though, even though when you look for a while, you can tell the lady is elderly. However, the first glance suggests she is young.
