Normally images of the backs of people do not work out all that well, but in this image, they seem to work well. I suspect that is because they are guiding us to see the rocky outcrop in the background.
I do find the title a little strange though. The scene is very bright for a sunset and if the flare at the right hand side of the image is where the sun is positioned, it looks very low and just above the horizon.
Looking at the image again, I think that it is the grace of your wife that makes this a fine image also (of course) your capture at the exact right moment...
