Yes, the layout by the way seems very straightforward and navigable, not too cluttered, easy to figure out how to navigate. I really love the layout of the top level nav bar, it feels like it sort of draws the page together to that central point, and navigation is a great place to direct the eye. You're not quite perfectly centered, if you fixed the banner perfectly on the center line of the nav bar it'd improve it a little (about 5-10px to the right if I had to guess).
I'm not sold on the colors entirely, I actually thought the earlier green/black/white scheme was cleaner. I'm not a big fan of juxtaposing rich blues and reds though, and that may be just a personal taste thing. If I were to use the blue and red colors I would try to integrate them into the page more, say by using some reds and blues in the headers and into the background, maybe a graduated pattern from blue to red, left to right, over the black - pinstripes or scanlines or something?
