Hey,
I looked at the source code for your homepage and the page is mostly made up of images. You need to redesign the homepage so it has a lot of text pertaining to keywords you want to rank high on. You also need to add some paragraphs of text to the pages that are linked from the homepage, but the homepage is key. Google looks at the text in the HTML code and then ranks it compared to other sites
Hope this helped.
Andy
