I had a quick look through the portfolio and the way you have presented each project is great.
The overall portfolio has a professional feel to it thanks to good use of images as well as showing stages from each step of the design process.
I particularly like to see sketching and prototyping skills which you have done.
The only thing I'm not too keen on is the way that I viewed them. I think it might be a better idea to have a look at combining the projects into one document but that's personal preference.
I think it might also be good to have a brief introduction page into the portfolio just to introduce yourself, but again this is personal preference.
You definitely have a strong base to work from, so I can only see it improving.
Good luck in your final year
