Good portofolio, simple, easy on the eyes. Two quick suggestions…
1. avoid putting siteplans on the gutter because information will be lost when you print and bind it
2. all of your images are about the same size making the spreads look dull. Make one of the images larger than the others so that the spread has a strong focal. Pages 4+5 works well (except for the siteplan being in the gutter)… there’s one large important image to catch your attention and smaller images to the sides that can support that main image.
Nice job!
