I'm really surprised that no one has done this before. That being said, I couldn't find a decent enough sized image to go by so I had to wing it and kind of go with my gut on what some parts of it looked like. If you see any parts that you think could be improved upon, let me know.
See if the attached is sufficient. Not a layered .psd (couldn't really see any reason to layer a single layer) but a .png with a transparent background. Did I mention that it's B-I-G?
