Nice project Luke. Your process is pretty well presented and easy to understand in a quick glance-able format. I like the cardboard mock-up and prototype you developed. Always nice to get physical.
One thing - I’d probably go back and put some more time into your sketch ideation pages. I see that you describe your thought process in text below each page, but I should be able to follow that process by just looking through the sketches. You could do this by giving a few key sketches (that were moments of realization) more hierarchy on the page. Possibly add some photoshop love to those to really pop them off the page and call attention to key features that came to life in your final design.
