The document summarizes what the author learned from completing a preliminary task of designing the front cover of a college magazine and then a main task of designing a full music magazine. Some key lessons included learning new software like InDesign and Photoshop, improving design elements like reducing clutter on the contents page, and better planning photo shoots by considering location and timing. The preliminary task also helped the author become less critical of their own work and more able to evaluate others' work and provide feedback.
