Masking Help

Hello there fellow kirupians?

I was looking at a few tutorials on FlashKit, in which I found this one.

http://tutorialized.com/tutorial/Ray-of-Light/2506

I usually try to do the tutorials, and then look at the example .fla in order to improve my work, but in this case none was provided. Also, I am not too experienced with masking, so my project is basically a failure.

I was hoping someone could try part of this tutorial, or just help in any way, seeing as I am not good with masking.

And help is much appreciated.
