The site seems very disjointed. It seems to lack order, and there isn't any visual hierarchy. Your logo isn't really popping out, like it should. You could try making it bigger, or make the colours more vibrant. Your text box to the right of the navigation should be a different colour, since it is orange, I assumed that it was just a break in the navigation. By giving it a different colour, you let the user know that it is separate from the menu. Also, the submit button reads "Sing up!" and not "Sign up".

I'd suggest getting rid of the next group of photographs which appear below the first set. They don't really serve any purpose, or maybe I'm wrong? You could use that space to move up the content area which seems to be neglected at the bottom of the page. Alternatively you could use this space for a video. You could also do with making the networking icons (Twitter, Facebook, RSS) more consistent with the rest of the page, they stick out like a sore thumb as it stands.
