Great job! I loved the overall feeling of distance on this shot, with the storm drenched sky and water disappearing into the haze. I love the motion of the water exhibited in the white caps. I love the sun breaking through to shed some rays of light on the beach and the trees. Thank you for meeting the challenge without leaving me to figure out how it met the theme. Raising my original score from a 5 to a 7. Above average shot.
You captured the rainbow very well and there is nothing I could remotely suggest for improving this image from a technical standpoint. Like several images in this challenge, your score will reflect how the image connects with the voters more than on technical issues.
