Wonderful images. I like your choice of placing the end of the pier on the horizon line in the first image, it makes the repetition of the pilings particularly strong, giving a sense of stretching out to infinity. In the other three images, I think the choice of long exposure to capture cloud movements in the sky creates an organic, abstract element that balances the careful geometric composition of pylons, sea wall etc.
Obviously going back to what you know best was a good decision. I think the Chilham project will come together once you can get past that point of thinking about it as a project, and past the point of "trying" to make images to specifically convey the sense of peace and tranquility at dawn. Seems like a lot of responsibility to place on the images and photographer. Once the "pressure is off", the images you want of Chilham will no doubt come.
