Too much of the foreground grass. Almost 50% of the shot is grass and completely uninteresting.
This was perhaps not the best subject to demonstrate the effects of positioning, although it does bring out another interesting point. The subject is, in effect, made up of two parts, the mother and the child. The mother is much bigger than the child, and if you look at the first shot, the mother is off centre, but the child is central. Similarly, in the second shot, the mother is central, but the child is off to one side. This has changed the balance of the shot, and, had the subject been a symmetrical shape, the second shot would probably be less pleasing. (As with the boat in project 6)
