Your process and final product are great, but as a hiring manager I have to give one one piece of feedback.

Your case studies are way too long and copy heavy. I doubt very many hiring managers are going to read them in their entirety.

If I were interviewing you I would browse each case study and then give YOU five minutes to explain them each to me.

They are very comprehensive and show your process, but with dozens if not hundreds of portfolios to review, a hiring manager will likey give you site two minutes at most.

Consider cutting down the copy and content so it is more digestible.
