1) The combination of the main music video and ancillary materials like CD covers, posters, and inlay cards was effective because it maintained consistency across products while avoiding repetition through varied camera angles and shots. 2) The music video genre blended grime, R&B, and hip hop by depicting the artist as sometimes stylish and relaxed, reflecting R&B, while also maintaining elements of grime culture through clothing. 3) The ancillary designs reflected the positive tone of the music video by depicting the artist in a friendly, happy way through vibrant colors and compositions rather than a typical sinister grime artist image.
