The mains page grabs attention, is fun, and interesting, while distinctly dividing the categories of the site.
The contact page is simple and is helpful in guiding the user where they need to go with the links being in the words. However, the font is small and may be difficult for some to read and clearly make out.
The work page has a very nice layout, and the images of his work are easily viewable. However, I almost did not see the "next button" and another viewer may miss out on Sagmeister's other works.
