Hi Abraham I loved your idea - when I first looked at your illustration the first thing that came to my mind was New Yorker covers. I think it's an elegant concept, easy to understand and a perfect fit for your chosen persona, Kristin. I would love to see more visuals for the other personas and other examples like this one, of people in a relaxed environment/everyday situation and how they connect with cybersecurity.
Hi Laura - I really like the concept of big brother. I think it's a good analogy and pop culture reference. However, as the brief says that they want something to make cybersecurity more human, I would probably go with another approach and try to use the big brother idea in a different way (maybe less revolting and scary?).
I also really like the combination of photography + illustration and I think it helps explaining how cybersecurity (something intangible to most people) affects our daily life. Good luck!
