First of all, you should put some thumbnail views on the main page, it's a bit empty. Also the blue background seems a bit disturbing, maybe you could change the shade a bit.
And of course, you should redesign the head banner to something relevant to your site.
The text colour and the background colour could do with being more distinct, and the header seems a little detached from the rest of it.
The website generally seems to be functional, but it's not high in the eye candy stakes.
