How can I improve this layout?

[Homosexual]

I'm in the middle of designing a layout for a Team Fortress 2 spray hosting website, and I want to know how I can improve the layout?

That is what I have at the moment. How can I improve it altogether?

really it's just a mockup, and i was asking design wise, like are the corners not round enough or are the subtle. anyway, thanks (:

[VirtualG]

make the bottom corners rounded on the content boxes but leave the top ones cornered

gradients, images, general layout and not random boxes, header, personify it, iconise it.
