Hi Jacob,
Leading lines are always a useful design element in a photograph; they direct a viewer to what you feel is the most important element in the photo, which in this case is the beach. What makes this leading line even more interesting is that you can see a lot of detail in the old timbers.
This photograph is however let down by two big factors. The first and most obvious one is the excessive colour noise which has been created by your use of a very high ISO setting, in this case 3200 ISO. Although I often use high ISO settings myself, I would not typically use a high ISO in a landscape situation. More often than not I would prefer to use a tripod and get my ISO setting down to about 200 ISO.
For this photo your exposure was 1/500th of a second at f9.5 at 3200 ISO. If your camera was on a tripod you could have then pulled the ISO down to 200 ISO and increased the exposure time to 1/30th of a second.
If I was even more inclined I would probably even drop my ISO to 100, increased my aperture to f22 (just to get even more depth-of-field) and I would have added a polariser or an ND filter to the lens just to increase the shutter speed even more – probably down to about a quarter or even half a second. About then you will start to see some interesting effects happening in the water.
Then all I would do is straighten the horizon up and you will have an interesting photo.
Cheers, Anthony
