I gave this a 6. It didn't wow me but the dramatic difference between the green and the blue, combined with the graceful wave form and shattering foam, make for a beautiful image.
The colour tones in this superb image are gorgeous - they blend together so well even as they are turbulent and churning. It appears such a simple image yet is done with elegance, finesse and impeccable timing. I love looking at it and how it seamlessly flows together. Bravo!
