I'm not an expert, it looks nice, however I reckon some images haven't got the 'banner' look as they appear a bit 'stretched'. Also, the blue is very vivid. The main navbar also appear a bit tiny (comparing to the body text) and is not in a standard place. The search box also should be rather higher (maybe higher or on the same level like navigation bar). there a no commonlinks and breadcrumbs. I'd also rather went for the 'printout' look, but that might just a matter of taste. I'm not a professional, just a student. Good luck!
