Its a great portfolio exhibiting most of your skills.
On the outdoor public seating, sketch page, Why is it written OUR ? it makes me think there are other people sketches also if its a group work.
If you have made the mockup, why not make some green patch for grass instead of going digital. The render is just pulling down the mockup beside it. Use human figures on one of the mockup. It would be great to see the process of you working, assembling the seats etc...(as said before above)
It would be good to see how many hours/weeks/months you took to develop your projects.
The PU Foam Blue colour mockup looks interesting, I think that should go fullscreen in one page to show the explorations.
I just realized there is lot of blank/white space on top and bottom, why not make your folio much slimmer, how transportation designers do to show their process ! Its a suggestion
For the Bird feeder project, the cover page you have not shown a teaser of the final product like you have done for other projects. Try to keep the layout and rhythm consistent.
For the footwear project, if you say 'What can a basketball shoe do for you?' Im curious to look for new innovative solutions. Where as its just styling. The quality is good. It would be good to see some annotations to justify what material, why this, why this feature etc....
For the final design, place the render in the center and enlarge it. Put the colour option at the bottom of the page. Because all 4 designs are the same anyways! and the ground reflection is almost half of your shoes, try keeping it 1/4 so that our eyes focuses in the center !
In the end there is no use of putting rendering and sketching page, because its clearly visible in your folio through your projects.
Instead you can have a page showing different medium and technique, eg/ ballpens, markers, colour pencils, charcoal....
All the best !
