These are some student portfolios from graphic design students and alumns from Endicott College (where I teach).
I’m sure you’ve heard that phrase, go big or go home. Your portfolio’s cover design is an opportunity to show what you are fully capable of. It’s a chance to grab someone’s attention. Make it bolder, take risks, leave an impression. Show that you can make cool, engaging, thoughtful stuff. Be uniquely you, have some confidence in your voice and you’ll be memorable.
