P.S. I recommend downloading this.It took ca. 19 hours in rendering and was only 26 percent ready (and hardly any visible change for at least 10 hours!). So I reduced it to 50 percent and most of the unsolved pixels vanished. It is still 4500 by 3000 pixels large.

Techno-Blah: I’ll add another picture with a Golden Ruler that I have once built in Cinema 4D. It is parented to the camera and I change the proportions to match the ones in the current picture.
When I arranged the figure groups I asked myself, why not place them in the middle. And when I saw it through the Golden Ruler-grid, I knew why. A lot of lines in the object arrangement match lines in the grid.
(Well, not as many as in Vermeers pictures, but I still found it interesting)

Thanks for looking!
