The clouds are splendid in this and radiate outnicely from the structure on the headland. The drab colours in the FG detract from the beauty of the sky and the sea, and cropping out the lower quarter to leave a sliver of land might be an idea to think on. It looks mighty steep at the edge but I am so tempted to get closer.

Innovative POV. Might want just a tad more space above the heads.

The rush and flow of the peat-filled water makes a great FG to the colours of the season.

The black and white does well to highlight the features of her face and bring out the character and how hard life tells on the people of the mountains. If you could combine this with the subdued contrast and darker BG of the colour version it will take away the bright area to the upper right and keep some of the detail in her hair.

The setting sun has produced a lovely glow to the huts and the surface of the pavement. The line of the huts and the edge of the promenade converge nicely on the figures walking out of the scene at the end of the day, adding to the solitary feel of the boy sitting alone. If I'd wish for one thing it would be that the boy were sitting a few huts closer to the front of the frame to give him a little more dominance.

Different and close to abstract. You can see that it is water, but the first impression from the thumb was that is was mist rising from a valley. I so slightly want to crop down to keep the top, bright corner out of the frame to enhace the abstract feel.

The sky adds to the surreal effect that you have already created with the processing.
I would be far more dramatic with my crop suggestion and remove the bottom half of the image to the bottom of the post on the left. Leaves a panorama, with the railings leading you from the corners of the image out into infinity.
