By full crawl do mean every page? Looking at your site we I can see we are crawling the site, but we are not indexing the entire site. Depth of crawl is based on a lot of factors including how your rank and the architecture of your site. I see that you have a sitemap in place, but that you don't have a lot of High Quality backlinks into you site. I recommend trying to build up the sites that link to you, (you can see some of these in our Webmaster Center) as well you could resubmit your sitemap to us. Also in our Webmaster Center.
