Try making the background extend right to the bottom of the screen as on my monitor, since the screen is quite big, it just stops about 2cm after the bottom text. Apart from that good, but a favicon would also be good. I like the way you have done the nav bar at the top.
Loaded very fast and high kbps rates.Nice onceagain.
But if you combine the 8 external background images in to one using CSS sprites loading becomes even faster.CSS Sprites loads once and thats all..relieves you of all bandwidth and very high quality user experience.
