Hi! I like your portfolio, it is of high quality for a bachelor student. You clearly show the kind of projects you are good at and have a good overall design ability and sense for form. What is missing from the projects is expert or user feedback in order to strengthen your proof of concept - without it, we cannot judge the success of your work!
It is good that you end with your best project, it is also a good idea to start with a good one. Your skateboard camera project is in my view better than the inhaler because it has more integration of form and interaction while remaining portable and fairly durable.
Your presentation is very good, in my view you are ready to show this to employers. All the best!
