Untitled by Andy Parkee

I took this un-posed image of my son Liam down at the beach one morning. He climbed onto a rock shelf and his silhouette suddenly presented itself. It is perhaps the most favourite image I’ve taken. One aspect I’m unsure about is how to best crop the image. I’ve already cropped slightly (the original is a fraction higher and a tiny bit wider) but am reluctant to lose more of the sky and not sure how to deal with the dark foreground.
