This is a nice blurred water capture. As you can see by the blurriness of the background bank, it is hard to hand hold these shots. I might consider cropping entirely onto the water, or include just a sliver of bank for perspective. If the blurred water is "blurry" you will never notice it.
Nice shot, good depth of field. Watch for distracting elements like the hiker and dog if you don't want them in the photo. I might shift the composition up a bit for a little more balance between foreground rocks and background shadows. Also, the horizon is tilted a little to the left. This is deceivingly difficult to get right until you notice it is several photos.
Nice clean sunstar which suggests your lens is free of dust. Perhaps it would be more effective off center...
