Simple, simple school porfolio site

I made this simple site in a couple of days at school for a project.

I was just wanting some opinions on what you think I should improve on. I don’t have any actual thumbnails of my work yet, so I used big pictures of dogs. The only trouble I’ve been running into is trying to get my 1,2,3…etc buttons to load the thumbnail. I have the question posted under Flash MX’s forum so if you think you can help me with that please post something there.
Anyways, any c&c are welcome.
