Wow, what an amazing sky, I don't how much is real and how much is PS, but it doesn't look overprocessed to me. The horizon is not perfectly level and that bugs me though!
Lovely work. To be hugely picky (but then the standard's so high in this challenge) - the top of the clouds looks bizarre, like you've taken too much of the punch of light out of them to get that definition, and that removes some impact from the darkness of beneath the storm. The boat gets too lost in the surf-line, also - i think ti would help for it to be a little fuller in frame, certainly at the available resolution here, which restricts detail so much. I think i'd have tried to get closer and lower, to get more boat and still the tops of the clouds. As I said, hugely picky though, those points.
Wonderful colours!!! Those greens and blues makes me wish I was there. I would have dodged the bottom pary a little bit so I could appreciate more the texture of the sand. Great picture nevertheless ... Good luck!!!
The colors of this image divides it into four sections: The brown ground, the green sea, the black clouds and the blue sky. Makes it very interesting, but in a way confusing, or thought provoking if you wish. But a good job at capturing so much in one frame.
Great colors here with a great cloud. This image in itself gets an 8 from me. However, had you thought of bringing along a ND filter? Coupled with this shot, a long exposure, thus blurring the waves and water into a misty softness, could have been very effective. Just a suggestion --- wonderful shot with an effective D&B treatment to it.
