Nice! The mood here is simply wonderful - the fog, the muted colours and the balanced composition provide a sense of serenity, peace. The light on the pier is fantastic - it seems to take on this nice glow. Graphically, this shot is strong with a good lead-in, the path continuing on to the pier, and hint of a distant horizon, adding some depth. The square crop works, and the shot is nicely framed by the tree. Well-seen, well-executed.
thumbnail not doing this one any justice, once enlarged one can it is lovely, very simplistic, sharp, calming. A little lifting of the fog to allow some detail in the distance I think would be even better. I am finding from experience that fog is verrrry tricky :)
