I was looking through my external hard drive the other day. This I recommend! Not only did I come across some pretty horrendous photographs of myself and mine from so far back that you can't help but cringe of certain fashion choices (photos I will spare you all of). I also found some of my course work from first and second year - check it out below! Nice to see that I've learned something during the past few year, eh.. ?! However, I do think the more primitive process you have in the earlier years of your design degree has a lot of value, there's something quite special about the naiveness.
Chceck out my portfolio for current work.
