The document evaluates how effective the combination of the main product (a trailer) and ancillary products (a film poster and magazine cover) are. It states that the three pieces are very effective because they all follow the same color scheme, font style, and genre (British crime drama), linking the pieces together. The narrative in the trailer also connects to the tagline on the poster. Ensuring the pieces attract the target audience by using conventions makes the work look more professional. The film magazine is the strongest piece as it uses many conventions like a medium shot of the main character looking at the audience to create a connection. Minor changes like the character's costume could improve the work further.
