Jon, I was blown away by your p/a post with this one - I love that you're playing around with it now.
Please know that I offer thoughts with all manner of humbleness. (is that a word?) I've admired and learned from your work for a long time.
To my eye, the p/a has a vitality and 'sloshyness" (since I'm making up words today) that doesn't carry over in the studio piece. Something about the shape and energy of the spill of white water over the near rock on the left, and I think also the jagged shaped top of the cresting wave that lends the energy. I do enjoy the warmer color, and that may make the piece more appealing. (I had a lady return a painting she'd purchased once, because it "made her room feel cold".) I can't decide about the addition of the round rock in the bottom, though, and am curious as to your reason for adding it. The white glare on the dark rocks... overall, I really enjoy the original most. I'm very interested, however, in your thought processes that led to the changes you made -
my .02, but I doubt it's worth that!!!

Thanks so much for posting these - I love to see how painters think and work.
