Thanks guys. There's still a few issues that I want to fix, but I'm getting closer.
Paul, the water does have some transparency, but the reflections overpower it. I could try raising the transparency, but I don't think it's going to do too much. I didn't really want to add more plants, maybe a few more rocks instead.
As for the bending tree, the only thing that animates in this scene is the water, but I don't plan on rendering an animation at 13.5 hrs a frame.
