Don't think I am fully using the technique mentioned above but it got me far
enough to randomise the shapes as in the attached. Also took the hint from
Thomas to change the edges of causeway to make it less even.

I did not add the clouds/sun/fog etc in this image it was just to check the
shape of the causeway and columns. Still more work to do but I am much happier
with this part of the scene.

Thanks

Sean
