The document describes the development and revisions of three Irn Bru advertisement posters. For each poster, the author provides feedback on what they like about initial drafts, improvements they want to make, changes they make in subsequent drafts based on feedback, and their feelings on the final posters. Some common revisions included changing fonts for readability, improving lighting effects, and incorporating their own custom tin designs. The goal was to create eye-catching, energetic ads that would appeal to target audiences.
