The headings right above the Lorem filler are a little light for me.
Not a lot of contrast with the background, or anything else near it.
Maybe you were trying to push the eyes towards the slightly more contrasting text, which in essence, is the most important thing there, but nothing on the page should really be "difficult" to look at like they are.
otherwise, very nice. Very clean, and good use of white space for the welcome. The nav links could use a little more padding, though.
