Interesting idea, John. Usually in a light situation like this you would wish for a fill-in flash to light up the face. You decided for the silhouette, and therefore I think it was important to darken the foreground so that it would be all black.

If this were my photo, I'd have "switched formats": from portrait style (upright) to landscape (horizontal) by cropping out large part of the sky and some from the bottom. Or I'd have left it square. But even though the sky is a wonderful, cloudless blue, I'd have given up on that in this photo. But that is just me.
