You didn't see it coming!
So... Spider and Juan have both extreme eye-shapes and the Galk usually have something from between theirs.
...hmm, how to explain this... Well. Us humans close our eyes downwards, so it's the upper lid going downwards but these guys have a bit too big eyes for that so both their eyelids just close towards the center of the eye.
There. And off to the doctor I am!PS: No, you're not allowed to copy this eye-shape to your creatures. |: © Me
