Seems like a solid suggestion from your friend. If the work you’ve been doing is more about realisation of products rather than conceptual, then show how many things you have successfully brought to market as possible!
I thought as you got a little older you would rely more on personal recommendations than putting the folio out there. Although now I think about it, there’s no reason to think that really haha. I’m pretty inexperienced, so I’m just trying to get my foot (back) in the door…I guess my folio would have a totally different look to yours.
