1 1 1 1 1 1 1, a million times, 1! I love the color in the water and the sky. Better contrast in the sky in #2, I wish you could bring that out in #1, but I'd still say 1. I'm sure the B&W fanboys here will disagree, though
Color, definitely. It is so unusual (at least for me) that I would certainly try to keep it and render as much of it as possible; you did an excellent job at that.
