The idea behind this piece of fan art was to find expressions of Bob in the comic book that illustrate the six recognized basic emotions in comics (and art), from which all other emotions spring.
So what it came down to was mostly an exercise in search, and then trying to reproduce the face of Bob Weiner as closely as in the comic art. I’m not too sure about the surprise and the disgust, though. It was the closest to the basic emotion as I could find them, browsing through Rebootus Maximus.
The colors were a bit of a puzzle too. Anger (red), sadness (blue) and fear (yellow) were easy, but what colors represent joy, surprise and disgust? Well, orange seemed to fit joy, and the other two colors (purple for surprise and brownish mauve for disgust) I found through Google search.
This fan art is made to help sell the trade paper back comic book Rebootus Maximus and to support the artist in his quest to grow a beard for as long as the comic book is sold through the website (see Beardus Maximus on PC Weenies).
That is all.
