Very, very good.
With a little of imagination, you can almost feel a tension, enclave fanaticism, brutality and unforgiving nature of the fallout world "of the past" - something so alien to player-is-stupid/babysitting worlds of the present.
Shame pictures (those that precede some game) are, as a rule, misleading about atmosphere what we eventually get in the game. Good thing this is fan art so there is none of those expectation.
