Phill, I think that the pattern works better, for me, if the image is cropped at the left edge of the vertical partition. I think that the left hand brightness competes with the pattern to the point of distracting from the image.
I agree that there is a bit of a "contest" between the two key elements in the composition and it never reaches a point of "stillness" but I am enjoying the debate! Well done.
Love the Photo phil the only thing that bothers me and I'm a nit pik. So take it with a grain sand is the out of focus in the lower left area. unless it is the scan.
