So finally after big gap I can show to you something near final image.
I painted copper details of cabins carcass in Substans painter, was very fascinatingly to add more and more leakings to make copper looks not brand-new.
Concrete materials are from Megascans. Also stones and from there and texture for grass.

I didn’t add anything alive (sorry for ppl who thinks that stones have soul) Sadly haven’t found yet nice cut-out person for right side of the image, but maybe that isn’t necessary for stable composition, what do you think?
