My idea for the fifth season postcard was to warn my sister from the dust storms that are going to hit parts of my country including my hometown, and that is because she has asthma.
For the postcard design, I drew a a view of my hometowne’s landscape with a a dust storm hitting from far away, as shown in the picture below.
On the other side, I wrote my sister a short message warning her from the weather and giving her some facts that I found online from this resource: http://phys.org/news/2015-06-powerful-pressure-sand-storms.html
