Thank you indeed, Robert! I shall probably add a second type hut in the 
next wip just to diversify a bit, and maybe some screens. Ideas still 
fluctuating.

Except for the mountains to the far right/back, this is just one 
height_field so moving/scaling is not practical in this case. At this 
moment there is a (ground) fog present for the distance, but rather 
thin, and it can certainly be improved, also with an additional one 
close to the water. Another idea I want to pursue is a thin cloud 
halfway the background mountains.

Very straightforward in fact, a sphere as sky_sphere (with emission 1 
and diffuse 0), one light, and using radiosity of course:

#include "CIE.inc"
#declare SunColor     = Blackbody(6500)*2;
#declare SunPosition  = <0, 0, -2>*10e4;
#declare SunDis       = vlength(SunPosition)*2/215;
#declare Sun_alt      = 50;
#declare Sun_azm      = -110;

#if (Area)
   light_source {
     <0, 0, 0>
     color SunColor
     area_light
     SunDis*x, SunDis*z,
     4, 4
     adaptive 1
     area_illumination on
     jitter
     circular
     orient
     translate SunPosition
     rotate Sun_alt*x
     rotate Sun_azm*y
     parallel
     point_at <0, 0, 0>
   }
#else
   light_source {
     <0, 0, 0>
     color rgb SunColor
     translate SunPosition
     rotate Sun_alt*x
     rotate Sun_azm*y
     parallel
     point_at <0, 0, 0>
   }
#end
