I like the structure of the wall in the back! How did you do it?

In these days of iso-surfaces and all sorts of new-fangled gizmos, that
would be the poor neglected agate normal (or were you being ironic? ;)
Ah, the poor normals. Relegated to walk-ons and crowd scenes - their stars
eclipsed by younger functions - who are badly behaved louts on the whole,
for all their modern appeal. Demanding thousands of parameters, and
exhibiting many flaws off-screen, before a satisfactory performance can be
coaxed from them. Sure they've got depth. Sure they've got outlines. But
where is the simple charm of yesteryear?
I'll stop now.

Erm, I was trying to be nasty. But I *do* like that wall structure; I'm
hopelessly short of resourcefulness...
The crystal of course is *very* beautiful! No irony.

My English is too poor to adequately answer your prose... :)

Nice.
I'll try area light, and I'll increase the light (is this good English?).
Why don't you try to make this crystal lie in the ground more naturally? I
think it would look great also in a plain plane with some reflection and a
skysphere:
plane {y,0
pigment {rgb 1}
finish {ambient 0 diffuse 0.5 specular 0.25 roughness 0.01 reflection 0.2}}
then:
sky_sphere {pigment {rgb <.6,.8,1>}}
then add fade_power 2 to the light_source and a quite short fade_distance.
Finally try adding another fading light_source (bluish) behind the crystal.
The light sources have to be quite near to the crystal.
Regards,
Jonathan Rafael Ghiglia.
