I had to do a series for art class, so I chose to personify the four horsemen using Mucha as inspiration.
Coming up with a non-obvious way to personify death was probably the hardest challenge in this series. I decided to give him a "beak doctor"'s mask, because of the associations with the plague, and death.
Also possibly because of all the Assassin's Creed I've been playing. Who said video games never helped them with school work?
