Good work on the site. To ensure it remains legally compliant, make sure you've read and complied with these rules: http://paizo.com/paizo/about/communityuse
Perhaps you already have, but I couldn't see the disclaimer anywhere, and I'm not sure if all of the artwork you're using has been released for third party use.
Hope the site gets a lot of use. It's looking promising so far!
