Actually there are shadows on all the areals some more than others, also on the chimney pots and stacks, but I wouldn't worry about it as it is really only noticeable I am sure Alan, with photographs, and only then when you really look hard.Ian, looking at the photos again I can only see one shadow. They were placed at the back of the chimneys so that they would be hard up against the back scene to avoid the shadow problem. A subtle bit of bending should sort out that particular aerial.
