What is happening here is that the girl is drawn in a confusing way: with childlike and also with adult traits. Also, the big eyes form a supernormal stimulus [1]. As such it is "hacking" into the brain of the viewer. Some people are more sensitive to this than others. In any case it distracts from the actual subject (the console software). As for work, I wouldn't consider it appropriate.

Oh, come on, that’s just the typical anime/manga style. You criticism applies equally to any software which has an attractive person as its icon as that would supernormally “hack” your brain as well. I see nothing about that drawing that is confusing.

Sounds like this fits with any kind of shape, color or combination of those (read as: logo) in any README.md that has one ... I wouldn't interpret too much into it.
