I live by the largest river in North America, although it isn't that wide way up here. I walk by it nearly every day, and in the winter it freezes, thaws, freezes. So I wanted to to paint what I saw, with what I had in the studio, and used brush and spray to do so. Did I see what I painted? Yes, in the mind, and memory's eye. Why a diptych? The floes are broken up, I guess. Then they join together, and break up again. Like so much else. Could you buy one piece, or the other? I'd rather you didn't but I suppose you could, with the right offer. Don't have the space for both? Rotate them!
