A dark day with the promise of a walk to the point to see something different. Everything in the photo works to give you the promise of a walk along the shore in this picture.
The dark, flat exposure works well in this photo. It combines will with the starkness of the scene and the cloudy skies.
Another strong leading lines composition, this photo also uses multiple leading lines in the composition. The arc of the shoreline is the main line leading the viewer to the point on the far left. However, there is a secondary point in the center of the arc that points to the bent tree on the center right of the image. The tree itself bends back toward the point of the arc however and echos the leading line of the shoreline so that the viewer stops momentarily at the tree and then continues along the path to the point. The tree at the center back of the photo keeps the viewer from wandering into the background and ensures your eye follows through to the point of the arc.
What Doesn't Work
While the exposure is a bit flat and it works well, there is so much detail in the rocks in the foreground that is lost that the rocks become almost inconsequential when they could be adding so much to the grittiness of the image. A slight change in the main focal plane with a bump in depth of field could make a big difference in these types of details.
