This piece technically has two inspirations. The first is Kyle Crawford, who created the first Mayday Parade album's cover art. His art inspired John Ryan Solis's cover art and other cover arts for the band. Solis's take was the inspiration for the drawing that is used as the base drawing. I do not have the source images for the drawing, but they were a picture of Derrick Sanders (the lead singer of Mayday Parade), a cemetery in Washington, DC, and a stormy sky. So using the drawing I created, I added my version of the iconic umbrella.
