Hm not bad, its clean, easy on the eyes, graphically simple to navigate, and would be easy to find what you need. I am not sure exactly what this is made with, if its strictly HTML, then it looks pretty good thumbs up!
But I really dont want to come off bad sounding here, just criticism, remember. I think its a tiny bit simple, its not 'too' unique. If you take a look at some CMS's out there, they could make something very similar in im sure quite a bit less effort you put in. That is if its not HTML (again if it is, great work).
If you ARE good at HTML though, and want to learn CSS (if its not already incorporated), I recommend looking at Joomla or Drupal. They are extremely flexible, and allow you to make some really fantastic looking stuff with quite a bit less effort.
Just some tips

. Keep up the good work though!
