Another example of the occasional fluid style of Martian face art is seen circled in this clip from a MGS image. Just to its right appears to be a curius Cydonia face with a "divit" in the center of the top of the headdress, resembling somewhat the direction that the Cydonia face archetype appears to have taken in the image from Eastern Candor.

I have much confidence that eventually a great deal more intriguing features will be found in the fine details of this particular image, in additional to more "coarse" stuctural forms.
