Here is the disk artwork that I have created.
A king cobra is a nocturnal creature and hunts mostly in the dark. The vision of a cobra is different from that of a human in such a way that they cannot grasp the shapes of the objects in the way humans can. They can only detect motion and rapid motion at best. That combined with infrared sensors makes them rather deadly predators.
This is the reason why the black on the disk is hazy and black- as it is my interpretation of a snake's field of vision.
So there you are.
