Just my 2 cents, but I think the user experience could be greatly improved. The design is not very sophisticated and the content on the page leaves the user wondering why they are at the site. These days, for a user to trust your site, it takes strong content and decent packaging. Content is key though, so my advice would be to try and find something different to say about the casinos you are listing.
On a side note, optimizing the graphics is a very simple task, if you have any time at all, that shouldn’t take you much. A 40k download is the industry standard these days.
