Many of the design assignments challenge you to design objects like posters, postcards, or book covers. Consider – What makes a poster look like a poster? What makes a book cover look like a book cover? It takes more than just putting words together with a photo. What distinguishes design from decoration? How does your work this week build on what you did in the previous weeks? How does design build on photography? How do design principles or elements of design apply to audio production? To video production?  “

I believe there are lots of things that make something that thing it is aimed to be. Like the poster, i believe it should be able to grab your attention, even if it doesnt, it still is poster, but thats the main goal I think as long as it follows basic criteria it still counts. So a poster may not need to grab your attention, but that should be the goal.
