OMG! I'm so proud of myself!   It's not as good as bagginsbill's but it's not bad!  I had to tweak the displacement value settings because I was getting spikey looking water at the settings recommended.  Here is my final render, followed by the screenshots of my material room settings.

I think the floor reflection looks pretty good if I do say so myself :)

Lights are my own.  3 infinite lights, all in white.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
