A well made first flash, BUT...
Based in your newbiness status:
Backgrounds = Good.
Music & sfx = Regular.
Character's graphics = Terrible.
Use of preloader = Excellent.
Now, for the pros, a nice first flash movies with something more than some sticks killing each other of some penises introducing themselves to some orifice. A background music that goes with the theme and mood, etc.
For the cons: If it IS a depiction of an important moment of your life, you didn't quite express it at all by using stick figures, you could have as well drawn some basic characters if you were able of drawing a background of decent quality.
Overall, it shall not be balmmed, good nice entry, please refine more your flash skills and make a remake of thes movie in the future when you feel you have more experience in the field of flash.
