As a Directory the site is OK, make sure all your links are working! That is important for a Directory.
Besides any links not working I like it, it loads very fast on a dsl here. I like how you have your link to code already for link partnerships which makes it very easy for others to link to you with no contact required. I been incorporating it on my website for about 6 months now and the response is good. You should be happy with the results.
