The design looks nice, and loads quick. Maybe you could add an introduction of your site, stating it's purpose and what it's for on the main page. I would highly reccomend you to code your content in HTML also instead of making it into images. This way you can get your pages in to the search engine. You should also think about arranging your layout better. Adding a horizontal navigation bar, footer, etc. Don't just fit all sections in on one page. Spread it out.
