I wonder what the view from the other (sunlit) side might have been.
Maybe gorgeously lit autumn colours?
As is, the silo looks a bit like a monolith (2001 Space Odyssey, anyone), becasue it lacks some definition in the dark areas to properly appreciate that it is overgrown.
The shadow in the frame can be considered a bonus, but there is probably not enough of it to make it a real deliberate feature.
(You stand fairly close, IN the shadow itself: when I include shadows resulting from backlit objects of people, I usually try to get the whole shadow.)
