Jim, the exposure on "before sunrise" is better than this one. Once you have the sun in the image, you need to over expose the shot to get the scenery exposed properly. In the "before" picture, I'd like to see a bit more depth of field, to hopefully, have the water in the foreground in focus. These are, afterall, landscape photos, and I'd like to see as much in focus as possible unless there are waves or something else which conveys motion. The wispy birds in the sky in the "before" image do convey some motion, but in my opinion, they really don't add to the image. On this picture, you have a flare in the water, caused by the refraction of the sun on internal elements of the lens. You can reduce flares by having the sun in the center (not always a pleasing composition). As an aside, if you happen to be shooting with the sun just outside the view of the lens, and find that you get a clearer image through the viewfinder if you shade the front of the lens with your hand, you need to provide that shade somehow or you will see a flare on the processed film.
In this image, there appear to be old pilings, which don't have enough detail to add much to the image. At sunset, they might make an interesting addition to a composition at this same location.
