The logo design is nice! However, the text around your logo makes that upper area look a bit too cluttered.. also: the content area is really plain, try adding some graphics to it.
Excellent logo but what are you going to do with all the space left on the right side? Either center your whole site, or maybe shift to wordpress.
I agree - center the site so the white space is evenly split. Logo up top looks very good - I am guessing you changed it since the other reviewers posted their comments. If you had further info or maybe added a comments area for others you could add additional content.
