Peter,
Overall I think your portfolio is good, but there are a few points that could use some tweeks.
As people have said on previous posts, you need your work to stand out from the rest. I think the stove project is the best laid out and shows the best examples of process . The concept development in this project is good and the user interaction (or card model) page is one of the strongest in the whole portfolio (IMO). You obviously have good skills in model making.
I think after this project the portfolio looses a bit of excitement, maybe its the colour (sorry, I’m English) choice for the background blocks. I think the yellow is a bit too intense for the parking meter project and takes the eye away from the project.
Have a look through some other portfolios and see how other people do this, I’m not saying steal their ideas, but take inspiration and work that into your own style.
I’m a particular fan of the logo on the front cover and well done for the work done so far
