1. Two stones on the white snow were chosen for the first type of composition. Remembering the exercise on the balance, I have placed a bigger stone closer to the center than the second one. I have also placed two objects so that there was a diagonal between them.
2. For the second shot I have chosen objects of the same size and placed on the same plane. As both objects are of the same size, I have placed them almost equally from the center of the frame. To make image more dynamic, I showed a clear diagonal between two objects and addition diagonal created by the reflections on the background adds up to the the dynamics of the picture.
3. For the third shot I have chosen more complicated points (the chimney and the lantern) as well as more complicated background. The image itself is quite dynamic, but I don't think the two points attract enough attention, when looking at the picture. It seems that the chimney is a bit too close to the edge. Generally speaking, the building looks more like a central object of the picture here, than lantern and the chimney.
This exercise proves that placing two points against each other as well as against the background is more complicated, than working with a single point in the frame. When changing the position, it is often that either the angle of one of the points or the background does not work. More variables makes the process of putting together the composition more complicated.
