These are the three photographs:

In this photo I placed the seal in the top right segment of the frame. I believed that it was a good position as it made the deal appear as if it was swimming away from the frame and although the body is not visible in the picture you can imagine it is below the water in the shot.

In this second photo I placed the bird in the bottom right of the shot as it seemed appropriate for the way the bird is facing and also the angle of the shadow. The stone shelf also provides an uncomplicated backdrop.

In this third photograph I placed the castle to the middle right, this was so that I could also get the feeling of isolation as the sea is all to the left and the cliffs are also to the left. It also helps draw the eye across the sea and up to the castle over the cliffs.
