The problem for me is that I am on your home page... then I dont know where to go? Am I supposed to just explore in the hope I find something I want to see? People on the internet dont really have time for that when it comes to stuff like this. You need to guide your user through the site a bit more. What is the purpose of the site and who is the audience? Where do you want the audience to go on the site? How do you make them do that? Theres different ways you can achieve it.. it can be implied in the design, or you can have little tool tips appearing etc.
Maybe I am just looking at it wrong but that is my opinion.
My overall impression of the site is a positive one though, I am only giving that small ciritism in case it can benefit you
