I got the subjects to throw lumps of soil of the cliff onto the beach below (making sure it was safe to do so and there was nobody underneath that could get injured) I then climbed down onto a ledge that was about one metre lower than the edge of the cliff. I found this to be a really exciting angle as it meant I could make the camera look as if it was buried in the ground. 

I really like the way the jet trails left by the planes overhead frame the images. This was a 'happy accident' as I could not have any control over the positioning of these trails, yet i feel they add a very subtle, yet powerful impact to the final image.
