I love the design. Its very sharp and easy to navigate. I'd be interested to see what an subpage looks like.
I like the fact that the lower part of the blue curved extends an extra few pixels on each side. At first glance, it could either be foreground or background to the upper part, but that extension tells the viewer that it's foreground.
The guy's face is a little creepy, though... it looks like his lips are warped.
