I think your notes that are already written down are really good, but here are some other ideas if you’re looking!
By having a picture come out of the pen rather than words, the illustrator is conveying that writing can convey images and evoke imagination: - a pen can be considered a symbol of writing, and many famous quotes/phrases associated with writing focus use pens (ex. The pen is mightier than the sword) - images are often associated with creativity and imagination - having a symbol of writing produce an image could show that writing itself has the power to produce images in one’s mind through their imagination
