Hey,
Just took a look at your website. It looks very nice, clean and well design. My first thought is to do with the logo that has been used, I guess I am not a massive fan of it for some reason.
A background hover colour on the main menu at the top might be nice? I personally would split the pages into complete separate pages, to cut loading time a fraction, but most broadband connections deal with most things these days
Apart from that, good job
