That's interesting. Wonder what the big black circle is for. Can't picture an exact shape for it yet.
I'm looking at it, and if it follows the same pattern at the normal human texture, everything except for the thing in the top left corner is the head (front, back, left side, right side, top, bottom), but that would imply that it's just a big head on top of some thing. However, the texture is pretty big, alot bigger than the human texture, so the ghast really will be big.
