I agree with Nate and Mathias about a single image in the header. I also agree about wrapping the navigation around the content.
I feel like the text at the top of the center column is tied with the image on the left. If this is the case, then this should be clear. May a border or background. Just something to separate it.
The three boxes on the right don't feel like they fit the design very well. You have some great texture in the top background yet these are very smooth looking. I would try to add some texture and refine the color choices to better match the earth tones you are using elsewhere.
I am definitely enjoying this design though! Good work.
