This is an illustration depicting the Devil's palace of Pandemonium. The palace itself takes inspiration from Italian and Babylonian architecture. All manner of foul and diabolical creatures inhabit the piece. There is a Roman feeding a giant Kraken heads out a bucket, while a Grim Reaper gives a demon lessons in scaring people nearby. Far in the background is a gigantic cyclops taking a lean against one of the devil's stables. The image is done with pen and ink, marker, and Adobe Photoshop.
