Shadow

I did have a neat idea for a piece sneak into my mind over the holidays--a portrait-oriented landscape, mainly fields and hills, with a shadow of some animal in the sky falling over part of it. You can't see any of the animal itself, only the shadow on the ground below. Overall effect would be of menace juxtaposed with beauty, hovering nearby, lurking. It sounds more like a straight painting piece, and I'm not a painter, so I'd have to figure something out, but I like the concept.
