Well if you wouldn't have lied and told us it was a ghost (or shown a hatchling picture at the start) I would have said at first thought I believed the animal to be a fire and not a poor example of a ghost in my original reply.

That said, she is an excellent example of a fire.

As far as the head marking though, it sort of irks me that people automatically shout fire when they see them (pun sort-of intended). There are several other mutations (vanilla and YB for example) that often have similar markings. Additionally normal ball pythons can have them. I have two heterozygous hypomelanistic females, a normal female, and a hypomelanistic female in my collection, all with similar markings (none of which are fires). Yes, it is a good indicator, but it is never a surefire way to tell.
