Abstract Window

I find this photo very eye catching.  The thicker grid seems to provide a structure while the thinner grid seems to contradict the thicker grid, breaking viewer expectation.  The light gradient seems to lend a sort of 3Dness to the image while following the compositional weight of the two grids which lend increasingly more weight as the grids get closer to the top right corner of the picture.  (I am not entirely sure if what I just wrote makes sense.  I am tired!).  I feel that this image is well composed.
