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

Yeah, you got it! I'm speechless...

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.
