I really like the layout and graphics.
The only thing I would change is the link color in the copy. I have seen time and again on all my websites that people prefer and are used to blue links. Blue makes them follow it.
I would experiment with the nav link colors as well. Red is usually hard on the eyes. Change it after a certain amount of visitors and test which color makes the visitor stay on your site the longest.
Apart from that, great site!
