First I wish to compliment that your site is Validated. I always encourage this and possibly go further by using a the 1.0 Strict or 1.1 Document Type.
I like the colours and a very clean design.
The search bar at the top could maybe have some colours with a gradient button and float it to the right just to give it some air.
I like your effect javascript drop down menu can I pinch that? Just kidding

When you hover over the links I think it would look better if the 2 colours match when you hover over the link with the right shade.
Where am I Section? Basically referring to the bar which currently says Home. I like these types of bars and maybe you should add a small icon to the left just to make it look more interesting.
As for the footer the link colour is too light for the footer maybe you should change it to navy blue.
