You're not using the full screen resolution available. There are extremely large margins on both the left and the right. Most resolutions computers use are 800 x 600 or 1024 x 768 so I would take that into consideration, as well.

Your color scheme is extremely dark. If you were to print out this as a paper prototype you would lose a lot because the colors you chose do not contrast well. A trick I was taught to deal with contrasting colors for For/Mid/Back Ground is to print it out in black and white.

I've been taught that for nagivation you should not have to scroll down at all to see all of the available options. Also, why is the header so big? You want the website itself to be the main purpose, NOT the header.

I don't know how I feel about your navigation being in the typeface Broadway. I think you should look up and use websafe fonts, like Times New Roman or Verdana for example.
