Gen Hagiwara - Frilled Neck Lizard (updated)

[JumPurge]

I just found this Frilled Neck Lizard by Gen Higawara on Flickr, first seeing it on dA.
I was doing the CP, found it hard, but quickly caught on.
Now there's the head. D:

Anybody able to help explain it? It's only this part diagramed. And I can't really understand without text to explain. :<EDIT>:

Crease Pattern :

Alright, I tried doing it again... yeah, it didn't work the best. >: Got back to the CP... even harder now that I look at it again. I can't get the creases to line up like in the base shown in the top model for help with the head D:

EDIT 2:

I found it all out. The creases on the top is a sink, that helps to seperate the two tops to make the frilles, and the diagrams on the head were smaller/bigger (I forget) than what I thought. It was strange. Ah well, I appreciate whatever help would have been offered. :3
