One of the most common comments I make on this site is the need for a focal point or primary subject... something that the observer is naturally drawn to. IMHO, many landscape photos seem to lack this. You have a nicely colored sky and ocean contrasted against a texture shoreline, which is great. But, now you need something to draw the viewer in. Even a tiny sailboat anchored off in the distance between the Jetty and the mountains in the background would be enough (I use this for illustration purposes... I'm not suggesting you should have broken the rules and added something after the fact). Hope you find this useful.
Beautiful image. Would have been nice if there was like a bird, person on the beach or a boat in the background. The rocks are ok but I think it may have been better. Still I like it.
