This is the best concept that I have seen you post on this site. Here are a couple suggestions to make the site even better:
Good work here, I love what you have done so far!
I would make the top pictures carussel and keep them one at a time - it is very confusing with so many images tight in your face. You can't seem the tell what they are when they are so narrow anyway - keep it simple and smooth, less is more ;-)
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.
The use of shadows is overdone. Wrong alignment in the content box. The title in the header should be aligned too. The position of the text must have some logic. Too much orange variations.
I cannot see the footer.
Well thank you! i like your ideas. This concept i made few hours ago for food brokers. Thank you so much))
