The first thing I noticed was that it requires flash player 7 to play.
for an intro like that, you should make it at least compatible with flash player 5.
The intro itself is very plain.... not sure if this was intended or i missed something... there are only 2 things I saw.
I didn;t hear any sound ( I have no sound), so I cant comment on that... if there's any.
I also noticed that it took a while to load for such a short animation.
Other than that it was good
