In order to make sure you cover all the necessary aspects, here are some extra guiding ideas for this question, but pay attention these should not be followed as structure, you can add more ideas than these ones:
How do your products represent social groups or issues?
In order to talk aboUt representation, you first need to analyse your work, as you did with the textual analysis before.
All the elements you analyse can relate to representation – for ex. having a minimalistic cover with just an image and discrete masthead could be representative for a particular type of audience and style. Also, particular photoshoot images can portray a particular social group – skaters – what visual elements are helping build that representation and how are the images combined with layout, colours and graphical elements in the digipak/poster/film postcard/magazine article, social media page to further convey that it is targeting an audience that appreciates the skating culture? (the hoodie/graffitti/skateboards/urban setting/handrawn fonts,etc). The same goes for music video/shortf film/trailers/documnetary in terms of props,color editing, settings and camera angles for example.
