This is a great looking scene now. The water and atmospherics are really good. For me the boulders are too big in relation to the trees, but that's just a personal impression, I'm sure.
Not being a purist I wouldn't be averse to making post TG alterations to that water running off the rocks - a wee bit of noise added here, a wee bit of clone-stamping there, a touch of dodge and burn here and there, tinker, tinker, tinker - until I've really got it fubarred.
