I love this. The consecutive circles as well as the spiral stair case just draw your eye in and give the photo depth on several different levels. And don't get me started on the perspective. It's absolutly gorgeous! The only thing I think could make this better is to go there either early morning or late after noon when the sun is hitting those stairs just right and casing those beautiful dramatic shadows.
Tis just my opinion and maybe it can't even be done with the way the windows are set up. Anyways tis gorgeous. Beautiful work!
