It's decent. I mean it's pretty clean, but it's a little long.
For a flash intro for a website it's pretty good, but if you plan on using it on an actual website (your own or for a client) consider having the flash be a header on the homepage and have the rest of the site be html. This generally helps to avoid frustrating people who don't have flash or who don't want to wait for the intro to load before entering a site.
I didn't give you a high score, mostly because for newgrounds this has no entertainment value and very little conent.
