I was in doubt about the trees because of their trunks. I may use others 
instead. The clouds are very satisfying. They are based on code by Mick 

Pragnell. I have not yet found when I downloaded the code nor from where 
exactly. However, it makes fantastic cloud scapes. If the origin cannot 
be found, I shall post the code as I have it today.

Ah, the Eifel! Yes, that comes indeed to mind.

Not sure what may cause this. I am not using exotic gamma settings (1.0) 
nor colours (mostly srgb).

And just an image_map and normal_map :-)

The metallic texture is by Explo Eristotle (many years ago) and one of 
the best rusty textures I know of. I was waiting for a comment about the 
bars ;-) Fact is that the railing is built in Silo using instances, so 
they look identical. Your comment is to the point and I should do 
something about it.

That part definitely needs some more work.

Right. More to do... Not too sure about the additions. I intentionally 
left them out.

We have to keep up the tradition of our POV-Ray fathers, haven't we? ;-) 
But seriously, I certainly would like to see more of these fruits on the 
POV-Ray market, like in the old days.

Really nice - I love the clouds in particular. :)

Have you tried using +AM3?  I'm thinking that stochastic sampling may 
hit areas that are missed by the more "orderly" methods.

It's very effective. Looking closely, one can see the checker-like pattern, but
the wider view is quite natural. I've used a similar technique in the past for
placing objects - using a version of a texture specifically designed for
filtering a random field of items.

My previous attempt at field boundaries was a random point graph, which
unfortunately required an external program - both for speed and sanity, since
SDL is quite unsuited to that sort of thing. I never got as far as making the
actual field colours, just the boundary walls (see attached). Sadly, as with so
many projects, real life distracted me in some way and it fell by the wayside...

It was on my todo list and I shall certainly use it. In de meantime I 
have just broadened the trunks and they are now more visible.

Yes indeed, this works quite well. You should try to take that up again. 
For my part, I have used ChrisB's Blockwall macro in my Islay scene 
(unfinished) a couple of years ago to a similar effect. That seemed to 
me rather promising although the macro also had a couple of quaint 
peculiarities, and it would be unsuitable I guess for a whole landscape. 
Interesting topics to explore...
