This was a quick design I did for someone on Reddit, who was looking for a re-imagining of the Gorillaz Demon Days album art work with Four of the Premier German Philosophers in the place of the 4 Band characters on the artwork. 

I set to work, and produced this piece for them shortly after, and with a bit of feedback to adjust some of the colours. 

Included Clockwise from the top left are Karl Marx, Max Stirner, Arthur Schopenhauer and Friedrich Nietzche.
