Your rendering got my attention right away, and then I couldn't think what it
reminded me of until now. Zardoz, the floating stone head from the 1970's movie
of same name. Didn't like the movie itself much, and haven't seen it in 20 years
or so, but that flying head and the idea of solving its mystery was good enough.
I really like how the faces and figures, pristine while situated into those
ancient-looking monoliths (for lack of a better word).
I was going to say there's a washed out contrast before, and while outside
yesterday I was looking around at how things aren't so bright and dark at late
day dusk. Which is the time of day your rendering seems to be, if that applies
at all.

Compelling composition ! I like it,... but, ;-) to me the creature's skin and
cloth, textures need more work i think the skin texture I cooked up here could
be a good fit :
https://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Render/POV-Ray/Sample_Materials#Skin_Light
The tong may be perfect though! and this may reveal after the rest gets
polished
The cloth, is a delicate issue, because it looks like your choice of tint is
meaningful, evoking the virgin mary traditional dress, so color can't be changed
too much, only divided into very close tints that can be assembled like this :
https://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Render/POV-Ray/Sample_Materials#Linen
but mostly it looks too plain, so it would benefit changing its reflection model
to oren nayar with a very high sigma, using a uv mapped fabric micro knit
element as bump map.

They remind me of something I've seen but can't remember exactly what. A
series of unglazed porcelain faces set into slate or granite.

And each one is different as far as you can make out.
The image is very atmospheric.

If I may comment, I am afraid those changes would destroy the
intentional 'blandness' of the scene, as far as I can judge.

Hi Thomas,
Thank you. I thought I would have a go at something a little more abstract, more
of a stylised representation if you will. The inspiration is from a couple of
images by surreal polish artist Zdzislaw Beksinski, one of my favourite artists,
but the imagery is definitely from the books. The sigils on the flying stones
are the big give away.

Hi Omniverse,
I had forgotten Zardoz! As I said to Thomas, the inspiration is actually from Mr
Beksinski.
Glad you like it. I love evening light and use it a lot. Interesting you make
the point about contrast as I adjusted it post render. Having been thoroughly
told off by clipka about using anything other than gamma 1.0 I am still trying
to adapt to it (which is one of the reasons I went back to basics).

Hi Mr,
Thank you.
I was going for contrast and simplicity. I actually do use a crackle normal for
the skin, form<1, 0, 0>, but the bump_size is less. I might try aoi and see how
that works. Nice textures you have there. May I borrow?
As you say, cloth is a tricky issue, particularly in this instance. I was trying
to avoid uv mapping altogether. I like to see if I can do it all in
pov-ray. I will try out your suggestions (which is a good excuse for further
tinkering - I am never satisfied).

Hi Stephen,
My thinking was Death Masks. But I do cheat a little. At the moment only the
first three are different. I repeat after that, though the 'tomb stones' are all
unique, (csg and intersection with an isosurface).
Creating each individual mesh takes time (expressions, postures, that kind of
thing.)
Glad you like it, and my thanks to all for your comments!
Cheers,
Simon.

Ouch!
But I know what you mean. I think it is the sort of image. That if you
add a bit more detail to one part. It will put the image out of balance
and you will need to add more detail elsewhere.
I think the image is finished the way it is. At least this version is. :)

Yes indeed. Adding too many structural details would change the mood of
the scene imho.

For a scene that doesn't use radiosity I think it looks surprisingly good.

The rendering is very good, I agree - I really like the subject matter and the
composition of the image - it grabs the attention right away.
I had that stone head bouncing around in my mind for - probably decades - and
couldn't figure out what it was that I saw it in. Then one day I was over a
friend's house, and he had Zardoz playing on his TV!
"What is _this_?!" I asked.
"Zardoz." - with a look and tone suggesting "Everybody knows Zardoz. Of course
it's Zardoz - what else would it be?"
There's a few more movies or tv shows like that, that I've since tracked down
and identified, but there are still a few more kicking around, that I can't
recall where I saw them or when.
Might be a good topic for pr-off-topic. "Identify this fuzzily recalled and
ill-described memory fragment of a thing I saw when I was a kid."
That will surely be a future raytracing competition topic... :D

Here is the basis for the landscape:
------------------------------------
#version 3.7;

global_settings {
assumed_gamma 1.0
}
#declare CamPos=<0, 50, 300>;

light_source {

}
#declare C_SkyPurple =rgb <171,113,161>/255;
#declare C_SkyBlue =rgb <161,184,213>/255;
#declare P_Sky=pigment{

pigment_map{
[0 pigment_pattern{function{max(0,min(1,y))}} color_map{[0
C_SkyBlue][0.5 C_SkyPurple]}]
[1 pigment_pattern{function{max(0,min(1,y))}} color_map{[0
C_SkyBlue*0.1][0.5 C_SkyPurple*0.1]}]
}
scale <1,1,2>
translate -z
}
sky_sphere { pigment { P_Sky } }
fog{fog_type 2 fog_alt 250 fog_offset 0 rgb <0.6, 0.4, 0.2> distance 20000}
#declare F1 = function{ f_ridged_mf(x, y, z, 0.1, 3.1, 8 ,0.7, 0.8, 2) }
isosurface {
function {
y - F1(x, y, z)*0.1
}
max_gradient 1.3
contained_by { box { <-200, -10, -200>, <200, 1, 200> } }
texture {
pigment
{
function { F1(x, y, z) }
color_map
{
[0.0 rgb <0.97, 0.65, 0.47>*0.5]
[0.5 rgb <0.98, 0.76, 0.56>*0.5]
[1.0 rgb <0.99, 0.85, 0.61>*0.5]
}
}
finish {
diffuse 0.7
specular 0.1
}
}
scale 500
}
------------------------------------
As I said, I went back to basics to see what I could come up with. Getting
bogged down in artefact removal, mesh misbehaviour and upping the values so that
you get really slow render times was beginning to hurl the hairs from my head.
As to the image, I tried adding texture to the cloth, and the only way I like
the finished result is if the texture is all but unnoticeable. So I am going to
keep it 'prawn cocktail' (See comedy show 'Goodness Gracious Me' for an
explanation of 'prawn cocktail')
Cheers,
Simon.
