Isn't it past the deadline for portfolios to be submitted at this point?

Anyways, here are a couple of superficial things I think would improve it. I say superficial because these are unrelated to the 'architecture' but might discourage reviewers from taking a closer reading.

I would suggest a different color selection for your diagrams on pg10 & pg11 to be more consistent with the subdued colors of the plans on previous pages.

the axon on pg16 would be greatly improved with some contrast in the color or by making it just a line drawing w/ a couple different line weights/types. Right now it just looks like plain 'revit' output, lacking in personality.

on pg18 the line drawings could really use some varied lineweights - the all one thickness flattens the drawing and gives the furniture legs just as much prominence as the line for the corner of a wall. You would also benefit from losing the binary grey/white quality of the lighting/shade, whether that's by using a proper rending of the sunlight or what I don't know. For that project the out of the box revit stuff is bringing down the otherwise nicely done physical model and plans/sections.

again in the library project the little vignettes on page 28 & 29 really need some love.

the most glaringly obvious thing to me is also a bit superficial, but something that irritates me a lot:

you prominently feature a large perspective rendering on page 25, yet the people have no shadows.

that aside, all the technical info looks great... though i agree with brer about the colors on pg. 10-11.

also, the superficial side of me wants to see more attention given to the concept sketches / diagrams so that i can understand your process better. admittedly, that's a somewhat petty request given the great technical depth in which you are presenting these projects.

i'm also applying to wash. u in st. louis... and i'm looking forward to finishing up my very last round of apps! (i'm applying to 7 schools too)
