What a super study, John. I especially like the tones and textures in the first and the almost abstract pattern in the last. That patch of blue is a bit distracting in the second I find. I wonder if you desaturate that a bit. What do you think?
I like them all and the second one is somehow the one I like the most without repeating Pete's words. I also find photoshop easier to handle then lightroom. A matter of taste I guess.
