Lucifer Effect

There's a theory saying that everyone is able to be or act evil under extreme conditions. Philip Zimbardo called it Lucifer Effect.
While listening about this on my psychology classes I imagined those evil thoughts and mindsets having shapes of crows. Unfortunatelly I 'suck the big one' at drawing birds...
anyway, here's my diptych.

pencils + black pastel (very old one, and very Czech.... though I have no idea what that have to do with anything)
