Building a Minuscule 1/700-Scale Diorama

Building and painting miniatures in 32mm, 28mm, 15mm scales is hard enough. How about a diorama, with figures, a truck, and a tree at 1/700-scale?

That is what Nikita of Art Models accomplishes in this micro-diorama build. The video is in Russian, but you can get the gist of everything anyway.
