Exercise: A sequence of composition

Exercise: Object in different positions in the frame

We are now looking at the relationship of a subject and its background, and how placement within the frame affects the perception of the image in relation to its background.
This exercise involved taking four photographs of a subject placed at different points within the frame. The background had to be large and even. The pictures were then compared and assessed on how the placement of the subject related to the background.

I have spent a lot more time on this task than I expected, it is not that I do not understand the concept of the exercise I just have had a hard time trying to find a suitable scene with an even background, in the process of finding one I have taken hundreds of shots, I now have a decent sized library of photos in the 'object in different parts of the frame' folder, and I feel I have explored this task considerably.
The photos of the Goats that I have decided to use are not the nicest pictures I have taken during this exercise, however I decided to use them as an example as they are quite uncluttered and reasonably even (apart from the wall in some shots) .
Of the examples above I prefer the pictures with the subject in the top right and top left corners, the scene is a reasonably dull one and I think placing the subject in the corner gives the picture a little more interest and actually draws the eye more to the subject than a centred placement. The large even foreground (background) gives a feeling of open space.
I like the first picture with the Goats just off centre (or centred) the least, the wall does not help matters but I think that the centrally placed subject in this scene is uninteresting, the back ground is even (ignoring the wall) so  it does nothing to enhance the scene.
