Sorry about the file size, but I feel I need it for my main question which
is...
So I've made this picture, I'm not quite happy with it so it's still a WIP
in my mind. Mainly I don't like the leaves on the tree and the surface on
the moon, any one have any ideas to make the leaves less 'flat' (or more
real) or to add craters to the moon?
Any other feedback would be greatly appreciated...

Sorry, I forgot to mention that the tree is the one of the example ones from
Arbaro (the newest release) and the moons surface is an isosurface.
The pigment I'm using is:
pigment{
granite
scale 2
color_map{
[0 Firebrick transmit -.25]
[.5 Coral transmit .25]
[1 Yellow]
}
}
and the isosurface is:
#local F_Base=
function {
pow(f_noise3d(x/3.157, y/3.157, 120), 1.078)
}
#local F_Wrinkles=
function {
pattern {
wrinkles
rotate 29.90
scale 1.602
}
}
#local F_Spotted=
function {
pattern {
spotted
scale 1/3
warp { turbulence 0.5 omega 0.55 octaves 9 lambda 2.8 }
scale 0.413
rotate <30, 36, 5.458>
translate 5.458
}
}
#local fn_Terrain=
function {
F_Base(x, y, 0)*-1.5
+ F_Wrinkles(x, y, z)*-.694
+ F_Spotted(x, y, z)*-0.043
}
isosurface {
function {
f_sphere(x,y,z,3476)
+fn_Terrain(x, y, z)
}
accuracy 0.001
max_gradient 7.55
contained_by{sphere{0,3477.5}}
pigment{White}
}
If that helps at all.

Hehe I agree deadline is not the end of life for an image
for craters I remember Johannes Dahlstrom's solution

All of the interesting parts are too dark. I suggest changing your light
source's position so that it's much more behind the viewer, lighting up
things in front of us. Then, since the earth will be more fully illuminated
that way, you might also consider putting a dim, bluish light that
looks_like the earth as a backlight for the scene.

On the moon you won't see any stars, at least as long as you are in the
sunshine like in your scene.
Good luck,

How so?
There is no atmosphere or scattering medium to occlude the stars,
only the contraction of the iris to damp down incident photon flux.
Of course, in this theatre of the absurd, there are trees on the moon, so
anything goes.;D

I don't know if it is the contraction of the iris, AFAIK it's a matter of
dynamic range of the eye. The sunshine is simply to bright to see stars.

Of course :-) Nevertheless seeing some stars in the sky distracted me more
than the rest of the scene.

It's my understanding that the lack of stars in photos from the moon is a
result of foreground lighting saturation limits and not from the slight
atmopheric scattering...

In proportion to other items I'd judge that your tree is 8-10 feet high...
leaves on a small tree like that would likely be sparser and larger. Leaf
size doesn't tend to vary much with tree size.
The grass is quite large in comparison to the blanket as well.
Heavy objects on a blanket would tend to compress the grass underneath and
wouldn't be so smooth, a height_field might catch the feeling better.
The horizon is quite stark, you could try focal bluring, or simulate weak
atmospheric scattering.
The moon surface is excesively ganulated, it could be a tad smoother.

This is a perty image, I kind of like it =)
