The document discusses what the author learned from creating a preliminary magazine project compared to their final magazine project. Some key lessons learned were the importance of research and planning, choosing appropriate photo locations and editing, designing more professional-looking contents pages with multiple columns of articles and pictures, using more interesting color palettes, improving coverlines on the front cover, and gaining greater proficiency with the photo editing software Photoshop. The author felt their final magazine looked much more polished and "like a magazine" compared to their preliminary version due to applying these lessons.
