A very nice composition, and I like a lot the landscape and its colors.
The castle grass is kept very well by the gardeners (or maybe by the
goats), it is curious that there is so much moss on the stones...

fully agree with PG regarding landscape and colours. not too far off views seen
in the Eifel. lovely.

Well... I was wrong-- the shadows do line up. My apologies, Thomas! My eyes seem
to be working better today ;-) Yes, what threw me off were the missing (i.e.,
too thin) tree trunks in the tree shadows, and not seeing where the actual tree
trunks meet the ground.
Btw, the clouds in the image look really nice, a BIG detail I didn't pay
attention to at first... even though the title is "Pending Storm", ha. I was too
busy enjoying other parts of the image :-O

This is a nice image. Your buildings are excellent as always, but I'm most
intrigued by the landscape. The patchwork of fields is very convincing - you
allude to a previous challenge scene, but I'm sure I've never seen this effect
before. How was it done?
I've experimented briefly with British-style irregular drystone-walled fields
before, and it's no trivial problem! As with many experiments, it dissolved into
an abstract geometric modelling saga woefully unsuited to SDL, but I hope to
return to it someday...
Also excellent clouds!
Bill

Extremely nice picture! Good atmosphere.
Once again, well done Thomas.
Cheers
Ton.

This came out well - the perspective / viewpoint works very well.
It looks very different between my 2 monitors. I'm not sure how to
independently change the screen colors/gamma on my laptop but leave the
auxiliary monitor as it is.
Most noticeable to me was the wood railing - the colors, the texture/normals,
and the algae growth (probably because it's in the foreground).
As others have mentioned, the landscape and clouds are very well done.
The rusted bars are excellent - that texture must have taken quite some time to
develop. (But perhaps they should not all appear to bent exactly the same).
The moss on the stone at the base of the railing is --- odd? Unnatural?
Perhaps also add a bit of space around the post bases (larger hole, shadow) and
a bit of extra growth and rot where the water collects.
The castle looks very clean. And perhaps add just a bit of texturing to the
little red roofs in the distance. Maybe some bugs? a bird? a farm cart?
And really - those clouds are fan-tastic.
Good work, Thomas. I'm glad to see some rendered fruits of people's effort
still being posted :)

Thanks Bill, much appreciated indeed.
I tried to find the old TC-RTC site again but - even with the Wayback
Machine - was unable to open it. :-/
Basically, the checkered fields are superimposed as a slope texture,
taking into account a b&w diamond pattern image_map. In the original,
the pattern was straight but I thought it would be more convincing if
that were changed to a more wavy pattern.
The code for the landscape is as follows (you can extrapolate for your
own needs):
//start code--------------------------------
#declare ImagePat = pigment {image_map {png
"DiamondPattern_05b_inverse.png" gamma srgb interpolate 2 transmit all
0.0 } rotate 90*x rotate 45*y scale 0.1}
//Map is necessary to place bushes and trees on the field edges:
#declare Map = pigment {ImagePat transform {HF_trans}}
#declare N_pat = normal {bump_map {png "DiamondPattern_05b_inverse.png"
gamma 1.0 interpolate 2} rotate 90*x rotate 45*y scale 0.1}
#declare P_field1 =
pigment {
agate
pigment_map {
[0.3 srgb <0.4, 0.5, 0.0>]
[0.7 srgb <0.3, 0.4, 0.0>]
}
scale 0.01
}
#declare P_field2 =
pigment {
bozo
pigment_map {
[0.45 srgb <0.7, 0.6, 0.0>]
[0.55 srgb <0.9, 0.5, 0.0>]
}
scale 0.01
}
#declare Pattern =
texture {
pigment {
average
pigment_map {
[1.5 P_field1]
[0.2 ImagePat]
[1.0 P_field2]//srgb <0.5, 0.8, 0.2>*0.4]
}
}
normal {N_pat bump_size 6}
}
#declare Patterned =
texture {
slope {<0, -1, 0> 0, 0.5
altitude <0, 0.0, 0>
}
texture_map {
[0.10 Pattern]
[0.15 Me_Rocks]
}
}
#declare F_HF_01 =
function {
pigment {
image_map {
tga "GC_Apophysis_06_hf.tga" gamma 1.0
map_type 0
interpolate 2
}
warp {repeat x}
warp {repeat y}
scale 50
warp {
turbulence 0.2
octaves 1 //[6]
lambda 1 //[2]
omega 0.2 //[0.5]
}
scale 1/50
}
}
#declare Fieldscape =
intersection {
height_field {
function HF_res, HF_res {F_HF_01(x,y,z).hf}
smooth
translate <-0.5, 0, -0.5>
texture {Patterned}
transform {HF_trans}
}
box {
<-0.5, -0.5, -0.5>, <0.5, 0.5, 0.5>
scale HF_scale * <0.99, 10, 0.99>
}
//rotate 90*y
}
Fieldscape
//end code--------------------------------
I suppose there are other ways to reach this, in particular by including
the diamond pattern as a function into the height_field. It is something
which I have not explored (yet) and I foresee a couple of difficulties
with that approach. In the present scene I just wanted a ready-made
landscape so that I could concentrate on the castle.
The pattern (Map) is also used to place the trees on the landscape by
means of the eval_pigment() code.
Hazelgrove, who also posted it here, I don't remember when exactly).

The original image where the code was used. I have not yet found
when/where the code was published.

Thomas,
great image, I like it.
There is one thing I wonder about with several of your landscapes, they
are desolate. Is that intentional?

Thanks indeed.

[grin] Good point. It probably is on a semi-subconscious level. Living
in a country that is a bit too crowded for my taste (although I am in
the less crowded northern half) is influencing my choices. Also, I have
always preferred to visit landscapes "far from the madding crowd" out of
taste and out of professional reasons (geology). Last (but not least) I
am not a great friend of humanity in general...
I like to use Poser and I have made a series of scenes in the past where
the human factor was present. This has drifted somewhat to the
background at the moment. Otherwise, cities do not interest me. Maybe
little ancient villages and - certainly - ruins, explain my (19th
century) Romantic nature. :-)
