Hi Brian,
Clearly the concept is brilliant and the execution is stunning, as we have come to expect from you. The "bustorama" concept has become your signature now and each one you do becomes a special piece of art in its own right.
One observation I would make is that the religious icons (stained glass, crucifix, bible and Christ figure) you have used seem to be more Western Catholic rather than Russian Orthodox in style. Russian Orthodox churches, even after the purges by the Communists, retain a very distinctive iconography that was immediately discernible from the religious artworks of the Western church both now and back in the 1940's.
This is I admit a nit picking point, as I love the entire scene, but I also know that you're a stickler for details and I'm sure you would want to get it absolutely right.
