I'm not a lighting expert, but I'd say you have it about right.

I've been thinking recently about what makes the difference between
soemone who can do landscapes and someone who can't, and I've come
to the conclusion that it's about the lighting.  I think that some
people are comfortable working with that kind of light and so are 
able to make progress with a landscape scene, whereas someone like
myself has to work close up in a confined space because I just 
wouldn't be able to light the vast area required for an outdoor 
scene. 

So now I'd say great you've sorted the lighting out, now press on 
whith some other aspects of the scene like getting a better mix of
texturing for leaves and grasses etc. 

This is all just my own opinion so don't take any of it to be 
authoritative on the subject.

This is very pretty! I especially like the water and the srubbery down
on the right. If I was to pick, I would say the closest leaves on the
ritght looks a bit stiff and could use som more randomness. The
shadows from the bumps in the sand are somewhat strong I think. Maybe
you could make the bumps smaller, cause the light in the rest of the
scene is too perfect to tamper with :)

Utterly spectacular. High praise. I can feel the cool air coming off the water
and hear the bugs and birds whirring.

The only two cents I could add is the observation that creeks and pools tend to
have lots of leaves and seeds, etc floating in them, and this detritus tends to
accumulate in the stiller areas near the banks. Lots of insects, too, of
course, although these might only show in a supr hi-res view.

You really know your stuff.

For some reason, this is way better than the last one. VERY realistic...

Wow, wasn't sure you could make it better.  :)

Hmm, my only criticism, the sand looks a tad pinkish.

        Very cool.  Pictures like this make me think of giving up
on raytracing 'cause I'll never get this good.  :-)   I wonder
how it would look if you used your skills and techniques to make
a fall (Autumn) landscape?

Try scattering media. The only reason the sky seems to give off light is because
the atmosphere refracts and scatters the light from the sun, resulting in the
light haze you usually see on the horizon and the blue look of the sky.
I'm not sure what that would do to the render time though.

I kind of like the previous plants. That grassy stuff. This still looks very
nice, though. Good work.
