|You asked for comments on your photo, I am not voting in this challenge so will give an in-depth review of it,
The very first thing that pops into my mind before I even click on the large image, is that it looked grey. Then opened it up, it is very grey.
The image is flat, there needs to be something in here that pops and I am not seeing anything.
The leading line, is there some-what. The two sides with the black rocks do draw your eye to the waves and the center point of the horizon.
You have a moody sky there, but it again it is grey, a little dodging and burning would have made for a very dramatic sky and would have given it some more dimensions.
What may have been a good idea would be a little vignetting, this in turn would have given you a leading line straight to the center, would have more drama as well.
Going into selective colours and popping the reds , would have brought out some more interesting tones in your foreground, sliding the greens, cyans and blue would have given you some more depth and colour in the sea area. .
Looking at the shot from a different angle would work well With a shot like this, taking the picture actually on the ground and having a good depth of field would have worked very well, that way you have depth and interest all the way to the horizon and there would be some excitement in there. Also, if you look at your sea, you will find two lighter lines from the sun, so shooting towards that, and just having the cliffs leading out to the horizon would have worked too.
I hope that this does not come across as too blunt.
