Ugh wow weird thread...
Anyways not sure if anyone else suggested this, don't have time to read all the replies.
Add:
body {margin:0; padding:0;}
to your css.
The way you added the background to the content area is very inefficient.
and the flower below the header doesn't look right getting chopped in half like that. Header could use more content. Navigation is somewhat annoying to use. And footer links move a pixel or 2 when you hover over them. Not sure if this is intended but it is quite annoying.
