The document compares a student's preliminary school magazine to their music magazine, outlining key improvements:
1) Photography was improved with better equipment, time, and subject matter for the music magazine, allowing for more professional-looking images.
2) Layout and design were more conventional and appealing in the music magazine, with single focal images, consistent typography, and proper conventions like page numbers.
3) Experience with the preliminary task helped the student recognize needed changes like simplified designs, proper cropping, and adherence to magazine layout standards in their music magazine.
