Love it. :)
The background image was a nice choice (but that took foreeever to load), the header is nicely done, the alt table colors are lovely and I love the buttons. My only suggestion would be to change the nav bar colors and style to something else and remove that ugly border around it. Also, please change the dropdown shadow for the ... whatever you want to call it (at the very top) ... to #333333. Right now it's just too noticeable and slightly distracting.
Gonna use this since, admittedly, using my own styles make PC feel a little tired.
