You've got a very nice use of color and gradients here. Your navigation is large and pretty easy to read/use. The cool blues throughout create a calming mental texture and I like the idea of the glass tubes for your top and bottom bars.
The design is a little Photoshoppy for my tastes though, especially in the navigation. Too many textures, gradients, and glows. I also lose your header and footer type in the glass reflection. It needs either a darker type color or less reflection on the glass. Also, where's your paragraph?
All in all, not a bad design. Good effort!
