Overall I like the site.
If your focus is to get visitors to subscribe I would make the part in the header for subscription stand out.
I am a big fan of colors on the site but some may disagree with me. I would put more color. Maybe pull some colors from the logo into the web design?
Other than that what I really like is that the simplicity of it. Its so easy for the visitors to come and easily navigate through the site.
Great work! :)
The logo seems to be stretched up a little bit and low in resolution. Maybe you may want to use a more attractive logo. Indeed as others have stated, when I first entered the page, all I see is a white page with navigation links on the right. It seems you have too much white space as the background. The entry page could definetly do with more text content explaining the purpose of the site which would also help your future SEO as well. I never liked videos embedded in sites and the one at the top of the navigation bar does not look too good either.
Best of luck with the site!
