A square on its diagonal becomes a lozenge shape that creates a more dynamic  composition as it introduces an element of instability. The curves of the metal table top and legs  participate in this instability as they relate to the edges of the canvas. The cast shadows create  echoes and continuations of these curves and arabesques and  the limited  mostly grey palette  of colours ensure that attention is not diverted  from them. The picture is held in a gently  dynamic balance.
