Overall, good design.. I'd bring the transparency of the snanlines down to just barely visible.. You also got some border alignment issues with some of the boxes.. The other thing I noticed, the header banner doesn't match anything on the page that I can see.. May just be me rather tired at the moment, but I just don't see anything matching. I think changing the colors of the header image would benefit the design.. Also, the text on there is not the greatest.. May be something else to think about..

Layout wise, looks neat the way you have it..
