The doodle of King, who is not a visual artist, is just incomparable to the one of Cocteau, who did work in film and visual arts. There's something charming to both of them, but the way trained artists can make even the shoddiest of their work beautiful to look at is something I am quite envious about.
Disclaimer: My doodles are shit.
In the article, Stephen King's and Queen Victoria's doodles are clearly using the symbolic brain, creating "drawings" equivalent to writing in hieroglyphs - the parts of the drawn objects are unrelated to how something looks in real life, only to what each shape means.
You don't need to become a professional of visual arts to overcome that style, only realize that you're doing it and practice drawing from pure visuals, without symbolism, and turning off the analytical brain.
In Cocteau's case, I would even argue that it leans more towards symbolic drawing, but with a more comprehensive visual library to draw upon- one that would've been developed from his profession.
Edwards does focus entirely on drawing from observation, but I see that as a necessary step on the way to drawing from imagination, in much the same way that you must first learn circuit analysis in order to do circuit synthesys.
My colleagues noticed that and I’m grateful that they specifically asked me to doodle during a workshop we hosted. Here’s a cartoon I did during that time: https://twitter.com/prashnts/status/1104060675205316609?s=21
I am not sure what it does for me, but I've been quite consistent for well over a year now and I do find all my old note books are quite fun to scan through.
