portfolio

need advice regarding masters in type design program

My application recently got denied for a masters in type design program. I learned from one of the jurors/professors that my portfolio needed to be 'less pragmatic and ordinary commissioned work'. He further noted that they were looking for work that contained more personal and experimental projects. This was my first time applying for a masters program and I unfortunately created my portfolio based on projects that I've done as an in-house graphic designer.

I want to reapply for the program next year but before I do, I want to ensure that I know how to best approach the creation of my new portfolio.
