Yes about the shadow, a little wider would work better. Or maybe not, I no longer trust the faint voice of my inner high school photography teacher. 20" wide is too small. Print at 40" high by whatever wide, mount it flush on Dibond, put it all by itself on one freshly white-washed gallery wall. If somebody wants to know "how much" they will have to ask the girl at the desk, the answer is $5000 (minimum). Don't think for a minute it wouldn't sell.
