What a pity that it's the amount of dust specs on your sensor (as many as there are on mine, I should mention, but I clone and clone these days so they won't show in the photos in the end) is the first and foremost I see here. Takes quite away from the image as such.
I like the fog, and I see that it is not easy to take photos in the fog. Apparently it is not easy to expose just right in conditions such as these. To my mind, the entire lower lefthand corner is way too dark, there is nothing to be seen there, and it takes up the whole corner.
Then I feel a desire inside me to see the hut a but further to the right, yet further from the centre of the image. I see, on the other hand, though, that that would even increase the amount of dark part on the left... so maybe this ought to have been exposed for for longer.
If you don't dare to clean the sensor yourself, maybe have someone in a camera shop do it for you who knows how to do it?
