The document discusses feedback received on different media pieces: 1. For a print advert, the image caught attention but the text needed clearer coloring. The background could also be brighter. 2. A radio trailer had an editing error at the end. 3. For a documentary, the ending music played too long and was unrelated to the hair topic. However, the documentary content and voiceovers clearly conveyed the hair topic. 4. Overall, the documentary interested many people but not all, and changes would be made if broadcasted.
