Very convincing scene Ulco!
Pity about those few bright spots on the mud, which looks great anyway.
Did you use a default shader or a reflective shader to get the muddy effect?
I'm pretty sure the latter, because that'd give more control.
There must be a way to control this better, but as you may know I'm not very fond of the way TG2 handles glow, specularity, reflections etc.
Well enough about that, the image is just good looking. About those reeds, did you model those yourself? I like them
