He's In The Details
The Screwtape Letters by C.S. Lewis
This book is presented as a catalogue of letters from an experienced demon, Screwtape, to his inexperienced newbie-demon nephew, Wormwood. Screwtape offers sagely (devilishly sagely) advice to Wormwood and seeks to help him earn his keep in the underworld by properly tempting those oh-so-corruptible humans.
I need to mention that Wormwood is pretty inept. Sometimes he has the reverse effect of his intent. I don't need to mention that Screwtape is usually exasperated each time he opens a new letter. I tried to portray some exasperation in the sketch.
C.S. Lewis always takes a wonderfully thoughtful approach to religion and morality. Through the two demon's correspondence, one can see how to actually avoid unwanted temptations, and enjoy some laughs in the process. Good stuff!
This sketch was done with inkwash and a tiny, tiny bit of Micron pen. Then I just digitally converted it to a nice red hue. Hope you like it!
