The main topic was "Sustainability", which is a topic I was avoiding since the beginning of my courses in the school. The reason I was avoiding this topic is because, I found that it is way too cliche to do something such as this, even though it is a important factor of our planet.
So, to make it interesting, I decide to do something with kids. By doing that, my design style would be way more open and free that having an audience which is more adult-like.
P.S : The audience is young ( Grade 5 - 6 )
