This is a highly modified scene built from my TG2 Voronoi Caustics Example.tgd, found in the first volume of my Public Library.
I spent quite some time making the sand blend properly with the stones, which are also a modified version of my 8 Layers of Fake Stones(0.01 - 1m). I'm still not entirely happy with the mix and I think there could be more stones below the waterline. I might reiterate this at some point, it was only a 1h 30m render without soft shadows, 2h 30m with them enabled.
Maybe when I'm bored enough I'll redo it.
The canoe is Tom's(Sonshine777), who was a great inspiration to me when I first started out with TG2, his renders would always blow me away! He doesn't post much nowadays but is still an active member, I occasionally see him in here. So, thanks, Tom!

You can find Tom's '2 Canoes' at
TG.org.
Fish is a free rainbow trout model, found here...

My
SandelO Shader is a work in progress that I'll eventually post, once I'm happy enough with it to be easily dropped into most scenes with minimum fuss.
Best viewed full size and, as ever, thanks for looking!
