fyi - you have an inline stylesheet in your index.html file and you have an external css
seems like an unnecessary http request.
<link rel="stylesheet" type="text/css" href="css/main.css">
also, you might want to stop the background from repeating by adding this to your css.
one more fyi, you have nothing in the website to tell search engines what the site is. All of your text is an image and you have no description tags. A site like this will never be found by major search engines. Try to use actual text whenever possible.
