on a quick look.. make the "Categories" not a dropdown. Much nicer if you see your Categories directly. And an easy to find "about us" and contactpage or something like that. to know whos behind the site and contact you.
your site is so basic features if you improvise in your text banner site wide features and colors its look better
Quick review, site looks good although few pictures may help. Error when submitting "Leave a reply" page. More professional banner may help too. Thanks, thecosmosphere.com
