In studying the history of art we learn how important the frame has become in modern art, especially tightly structured "hard edged" paintings like Ellsworth Kelly and Joseph Albers. I seen in this image the photographic equivalent of such painting which relies on abstract principals bringing emphasis more to proportions, shapes and their positions precisely aligned with elements of the frame, especially the edges and with the strong diagonal pointing at the upper corner. Your practiced eye is working well to abstract purposes and this looks great in its simplicity and weight provided by well-judged proportions. -tv
