thanks Erik, I was working out how to say that a few hours ago

John, the subtle tonal differences work much better for me in the colour version which I like a lot

In the B&W my eyes are immediately drawn to the Black post at the end of the walkway and then have to work at seeing the entire image.
In the colour version my eyes started at the bottom and worked my way up through the entire image. Not sure if that is good or bad but if there as something more interesting where the black pole is, person , boat, wreck,.... I would probably be happier with my eyes going there first

. In a different composition the walkway would be the leading line drawing me to...probably disappointment
