It’s taken 22 days and I don’t see any more benefit from rendering the image.

I can see the hat on the man in the middle, can’t quite make out the bouquet of flowers but with all these renderings if you squint a little you get more detail ;0)

This is four hours into the render, I’m starting to see people on the stage and legs are starting to form.
I can see maybe a proto-face with the beginnings of a nose. Still lots of work for this render.
