Wow! Love the last ones there!
You're welcome Bobby. What I would do now is lower camera until a meter or so above water level, and reduce translucency on those bushes (?). What I see here in the reflection of the clouds sometimes troubles me as well, the grain looks much more pronounced in reflections than in the actual clouds. Would that have to do with subdivision settings (being 0.25 instead of near 1)?
Actually a very cool setting, Bobby. But please build up those stones by yourself and don't just drop in some tgc. They need more definition. If you blow the stones up (I think it's in those stones, as I once told Bob how to get them rounder), add a XYZ shader after that pf for a next tiny pf and will most probably get you finer detail, which you otherwise can't have.
