Thanks for the comments.
Something there of everyone it seems.
Maybe the higher contrast in the curves on the top RHS of the image is drawing my eye away from the overall arc?
I see what you are saying the flatter lead ripples better suit the overall slightly high key look of the images.
Taking the shot a bit later when some of the energy has gone out of the rear ripples so they are not as steep and making a shadow would probably have been the best solution.
B+W can capture great subtlety but also add emphasis that would not otherwise be apparent, such are its strengths and challenges.
