I'm not sure if you plan to take this site further, but there are definitely some design improvements that you could consider. For example, putting writing directly on a background image is generally not a great idea. Also, the site should have a cohesive feel to it. That means going from one page to another should maintain certain elements, such as the menu being the same and in the same place, the color scheme being similar, etc. There is a balance you have to strike between variety and unity in a design.
Take a look here to see examples of good design:
