Needs progress images and dirty napkin concept sketches.

Everyone thinks portfolios are just a collection of final renderings... this is wrong.  Grad schools want to see how you think and solve design problems.  They don't care that you know where the rendering button is.

As Non Sequitur said - more process, less renders. How and why you arrived at the final project is far more important to admissions committees than the design itself (Though the design should be very good too!) Each image should be excellent in its own right and not put there just because you needed to fill a space or sell a part of your project. All project narratives should flow - there's still a stop-start rhythm to the current layout visually and narrative-wise. I think you have a good idea of hierarchy in terms of the sizes and placements of the images/drawings but the content itself can be improved - I don't know what that photo of the model's corner is supposed to be telling the reader, for instance. If a project has good drawings, make those bigger - ditto other media. Each project can showcase a different facet of your design thinking/process.

In addition to what was said about, I think it is important that all text is clear, legible, and at a readable size. The drawings labels, especially on pages 6-7, are very small.  Have someone read through the project descriptions and give you feedback.

Overall, think about hierarchy of your images. You have multiple full page renders, but then the plans are very very small. It is nice to have pretty pictures, but you also want to show you understand space and can depict space in 2D.
