Sorry Daniel, I was on holidays and couldn't reply before.
First of all, I'd limit the number of projects, you have some like Energy or Revive that aren't well explained and lack of a clear and appealing presentation. If this is a portfolio you're going to be sending to companies, I'd include max 3 - 4 projects.
I also think that in general you need to improve the layout of the presentation, putting bigger images, a sort of guidance for the viewer though the pages and put more images of the sketches, process and layout. The dyson and collaborate projects are interesting but, in my opinion, the presentation lacks fluency.
