Extremely nice image, Bob. No wonder it takes long to render with all the fine water displacements. I like the addition of the veggies. One thing; the highest rocks (back, left) also have reflectivity, but maybe you should lower that a little or increase fuzzy. The waves just aren't high enough, IMHO, for those rocks to be totally wet.
One way to reduce render time would be to set transparency to 0, and/or use a fake underwater color scheme. At least for the distance, and add a transparent water shader without waves for the closest parts.
