These are good points. Of course, a title could be helpful. I thought I'd make this illustration a part of a short comic strip. Maybe a person is looking at his/her email client wondering where the "Encrypt" button is, because, everyone talks about mail encryption. Because there is no button to be found, the person thinks: "That seems to be very complicated. So who cares, it can't be that important." Then a friend shows up, presents the roadmap, saying something like: "Look, it's not that complicated. Let's set it up."
Estela, thank you so much for your feedback. I added a quick second draft which tries to put more emphasize on the contrast of both sides by showing more of the room and thus contrasting more stereotypes.
