HELP! Tri-Headed Dragon

[Irontheater]

Okay, so hello all, i am new to these forums, and i am relatively new to origami and paper folding. I used o do some very simple things, but they don't stand a chance even against the easiest real origami.
Well, i have been challenged by a buddy to do the Tri-headed Dragon, in one month time, and if i did succeed he'll be buying it for 800$, so, i want to do it, just to prove him wrong (and to take 800$ lol)

So here is the one he wants me to do: http://dev.origami.com/images_pdf/dragon_3heads.pdf

I will be going step by step through out it , and whenever i find a difficulty i will be posting here, and i really hope you would help me.

Alright, what you want to do there is just lift that flap, and squash symmetrically first.
