Hi Caleb,
Thanks for sharing.
The idea of the portfolio is good - explaining the projects, showing some process and a few hero photography/render shots.
However you are presenting it like a stamp collection - be bolder, tell a story for a project, use more space on the page as well.
Instead of showing a little bit of everything select 3-4 of your best projects and present them more clearly. You can work on graphic design and typography as well.
It is OK to use more pages, as long as it is under, say, 60 and you can simplify it by dividing each project section into a page about the intention/orientation, one with process and one presenting the results, with no more than 4 images per page and a paragraph of text.
I like your ergonomics study the most, there is some cleverness.
See if you can build on that and reach creative solutions that are marketable, usable, beautiful and manufacturable.
