The first thing I started clicking on where the blue sqaures right next to the link, which gave some visual feedback, giving me the impression something did not work as no content showed up .... a few investigating moments later I clicked on the text link and content appeared ....
You might want to look into making them blue squares clickable too.
Other then that, it looks nice, lots of white though, perhaps look in to centering some content in the middle of the screen.
