I think this is a Ghost Face.
Does it look like a deformed face to you?
Jenova is deformed.
The Ghost (or reflected?) face is deformed.
I think they are connected in some way.
Ok, I hope this proves something:
Some of you guys have assumed that the right side from the original picture looks the same as the left side. Well, I've enchanted this picture to make it look more clear. What does it tell you? The 1st side and the 2nd side look absolutely different (not the same colour).
The colour of the background behind the white dot is different than other areas. It looks like a round of his right shoulder.
