I took a look on your site, too. The theme looks really good to me.
The only thing which confused me is the login-window. Usually, I open my internet browser in a small window, then the login is over the banner and over the first two links from the menu bar.
If I open the site in a big window, the login is far away from the site content and it is easy to overlook.
Maybe you could add a link where users can login or register to the menu bar or add the login on the index site.
Hope this would help you
