It's probably worth mentioning that the model is a David Krentz Shapeways piece. You've changed the pose a little for your illustration, though (the Krentz piece has its mouth WIDE open).
@Marc: I was going to save the mention of the model for when I post its pictures. :D I simplified many things to a near bog-standard lateral view just to make it easier for me as a colour study. Then again, I also added a dewlap, which the model does not have. :)
