Hi Bronney Hui, your idea of oversharing on internet is interesting. But i feel your implementation lacks the necessary context to interpret your message. Unless you put an explanation explicitly, it can be hard to draw its connection with cybersecurity. One way you can easily illustrate oversharing is by showing someone's twitter or face book profile stuffed with unnecessary updates about themselves.
Aesthetically the best artwork i have seen on this website. You beautifully illustrated the complexity of modern world. But apart from that it offers less clue as how to interpret it. Whether this complexity is helpful or destructive ? How does it create conflict ? If you can answer these questions with your beautiful illustrations, it can add clarity to the message your artwork is trying to speak about.
