One of my all-time favorite works is “It Has Come to Pass” by Sergei Lukin. Imagine contemplating the opulence of the palace, knowing how the peasantry lived outside. Knowing that the revolution had triumphed and that it was time to build a future for everyone.

Some honorable mentions:

There’s a user named Fan Wennan who does concept art. It’s truly amazing:

“China: 2098”
