Looks nice. Simple, which is perfect for a site dedicated to just provide information, but just enough design to make it visually pleasing. I would definitly stay away from the temptation to add any design elements to it.
Good job.
Peace
p.s. what is the font you’re using for the menu? Looks kinda like something I have, but not quite the same. I like it.
I think there’s quite a bit of wasted real estate there. You could happily make the space in the middle a little wider and still not loose the desired effect.
