Looks fabulous Ryan!
What really makes it work for me is the water.
It looks really glossy and wet

Often I find the water in TG2 very ridged and plastic looking, but this looks nice and shiny and appears somehow smoother rippled. (although you can see ridged parts of course, but still) It's a matter of settings of course + camera angle.
You might even consider rendering the bottom part again at detail 3 to get 0.75 detail equivalence for the stones.
I shall take a closer look at the clouds at home as my screen on work is not so well at displaying subtle contrasts and stuff.
Cheers,
Martin
