Below: the first attempt at a "finished" picture, done using a fountain pen with pencil over the top. I thought that it looked too laboured, especially the egg yolk, which seemed too dark.
... I'd be interested to know which of these three pictures people like best -- the one that I consider to be the "finished" one -- the simplified one with the green background (top) -- might not necessarily be the one that viewers connect with. Let me know!
I have also been admiring the work of the French artist/illustrator Marie Delafon lately. I wonder whether I was thinking of her work while I was doodling that day?
