Browsing your site from my laptop running 1280x9something resolution, 2/3 of the page is just your header. Add in a couple tool bars, and I can barely see the top of the girls hair in your first post, let alone any other enticing content that encourages me to scroll down. You would probably be surprised at the amount of visitors who do not even scroll down to see your calls to action, blog posts or anything else. You have 3 seconds to impress them, put the space in your header to good use!
