Tips for creating a portfolio when looking for a job as a graphic designer

Hi! I recently graduated from college and am now looking for a job in graphic design. Can anyone give me some advice on how to build a portfolio? I quickly put together my first portfolio — should I change it? What can be improved? Should I present each project as a separate case study on Behance, and will that have any effect? behance.net/gallery/255816453/portfolio-graficheskogo-dizajnera-2026
