You have to see it in the magnified picture. (Backtrack through previous posts)
To me it looks like a pale rectangle with a funnel coming out of the top. There is a shadow that looks like a person behind it. (In the Owl eye on the right.)
Yes I did see that in the right owl’s eye, as I said, of a person with arms crossed. Not able to discern as much detail as you are. Not saying you don’t, just that I don’t!
