One gripe with this design is that this page can't be scrolled on a PC. Or rather, it can only be scrolled vertically. To scroll horizontally, you need to grab an auto-vanishing single-pixel scroll bar. Although that's not really your fault as much as the browser designers' fixation with minimalist GUIs.
I also think it's difficult to have these many images in an interface, especially brightly colorful images of vastly different sizes with faces. They are all powerful attention attractors, and as a result, and the result is the (excellent) structure of the website doesn't quite come to flourish as much as it could.
But as I said, search UX is extremely difficult. This is a cool new take.
