You've got a good start here. However, this is by no means a finished animation.
If you want to learn how to not have the animation repeat, you must first have a preloader. You can get them on Newgrounds, and putting them in your first frame will automatically stop the movie until the Play button is clicked. When the movie loops around, it'll stop again at the preloader button.
Alternatively, you could convert this to a video file using Swivel, and as such, could also upload it to YouTube, but YouTube is for lame-o's, and you should always submit your stuff here first.
Best of luck.
