Hi Timo,
I like the first shot a lot, great mood, beautiful detail and subtle tones.
I like long exposures and the misty water effect it can produce, not the complete cotton wool effect as seen in some images, but the soft ethereal detail as captured and shown here. I also like how the elements (receding rocks) within the frame, form a decreasing perspective lead-in line towards the dark brooding sky in the background. The only suggestion/comment I would offer, would be to leave the vignette as is, but open up the top centre of the image a little, just to add more emphasis and light to the far distant ocean and skyline, to create even more depth.
But even as it stands, the image is excellent and delightfully brooding.
Bravo!
Dave
