In October 2002 Genady Obukhov posted barks to the p-b-sf (several 
postings from October 4th, 6th and 16th) that may be of interest to you.

Me too. I believe it is spot on.

The figure is just a placeholder I use for the (approximate) scale of 
shapes in the scene. It will disappear in the final version. I am not 
always very strict where scales are concerned and do much just by 
feeling or rule of thumb. Only in serious cases I set out a strict, 
basic, scale dimension for the whole scene.

I am quite satisfied with the ice crust too. It took me as much time as 
the whole remainder of the scene to achieve. :-)

Thanks indeed Michael! I dived into my archives (cough! cough! Damn 
dust!) and found a trunks.pov from November 2002. I shall look further 
and delve up those files you mention.

Yes, the file I have (trunks.pov) seems to be the final version of 
macros. I am not entirely satisfied with them. Especially when varying 
the BaseRadius and TopRadius values, there is a fundamental problem with 
the F1 functions which do not adapt correctly/linearly the depth of the 
bark accordingly. I shall look into that at a later stage maybe.

A promising image!
Interesting also the works of Jean-Pierre Ugarte. Some of those reminded 
me the lithographs of Antonio Basoli (e.g. 
http://www.italianways.com/lalfabeto-di-basoli-e-la-storia-infinita-2/).

Thanks Paolo! In turn, Basoli reminds me of Piranesi of course, another 
of my inspiring artists.

Good snow. I assume you used Gilles Tran's MakeSnow macro.
How many snow particles did you use?

It is a combination of a layered texture (most of the landscape, 
especially in the background) and Gille Tran's macro where it matters.

The number of particles is variable according to the surfaces exposed. 
So for instance, I added snow to the foreground landscape and that took 
800k particles; the heads got two layers of respectively 15k and 10k 
particles; the fir trees got 50k and the trunks in the foreground got 
two layers of 3k and 5k respectively.

I also used varying values of Size and Thickness.

It was surprisingly easy to work with Gilles' macro (it was, I think, my 
first time) and experimenting with different values for the settings was 
instructive and comprehensible. Parsing and render were pretty fast too, 
with the advantage of faster PCs than when Gilles wrote his macros. :-)

A very good image.
With such a subject a black and white render would also be good, like a 
lithograph.

Thank you Paolo. You are right. I may explore that too and shall keep it 
in mind (I like black and white pictures!).

it is very accomplished, the ladder is real clever, adding .. interest.

also agree that black+white (sepia?) would be worth seeing.

(ought there not be a little snow on top of the truck's spare tyre too?)

I know it's your model, and who am I to argue, but are you sure?  :-)  the
round-ish white "ring" on the (in the UK) driver's door looks like a hub, and,
magnified, a roundish outline is visible.  or so it looks.  see included.

As this is the ancient Soviet Zis5 truck (brought graciously by Taschen 
btw) there is a round sign with the number '503' painted on the door. 
The spare tyre is underneath the (load)platform.
