Tutorial on how to create a broken glass effect...

So... For my first class montage I created a broken glass effect... I didnt know how to do that so I looked online to see I could find a tutorial... The tutorial is good and it teaches me what I wanted to know, but I feel as though there were lots of things I did not need.  There are about 19 steps and I think I had to figure out what I  needed and start at step 11 or so...

Check it out and tell me what you think of this tutorial... The link is below.

Yay, or Nay???
