I didn't like the design of the original card, but did like the concept of it referencing judgement day, so I started from the same concept. I decided to turn the coffins on an ocean into graves on a hill, and the angel trumpeteering became the souls/angels of the dead rising into the kingdom of heaven on ressurection day. I also depicted them as innocent white doves instead of angels, an image I then also used in the Hierophant card.
I paid extra attention to have every grave be unique. It'd have been easier if I copy pasted, but I'm _very_ pleased with the result gained by making them all different designs.
