Geometric - grid in a circle

My blip subject is a window in a factory/storage facility. I looked at and photographed it from as many angles that a high fence and vegetation would allow. There was only one place from which I could get the window to reflect the tree. Other spots gave yet more straight lines or a jumble. What I've posted is by far the most effective, in line with Ingeborg's suggestion of introducing the organic into the formal.

Thanks for hosting Ingeborg.
