The 2nd illustration for the ttrpg scenario I cowrote. There's 3 in total.
I designed this as a fusion of old playing cards and the tarot, with the Joker, the wild card, also being the Fool symbolising new beginnings and journeys. He's in the Hanged Man pose to symbolise sacrifice in order to move forward and seeing the world differently as you walk your own path. The Hanged Man is commonly thought to be hanging of his own volition. The train is because the scenario takes place on a train, and the player is trying to go to a city.
