Great catch. I can see the triangles and the squares, but where is the circle ?

The joint of the crossings on the ceiling are circular.

Just as a side note, the thing that looks like a person in bottom right is actually a statue of some saint.

Ah ok ! Thks. Without High res, it's hard to see it.

Yeah, I put in a red flag to see if I can't upload the Hi-Res.

You don't have to put a red flag, just go to "My stuff" -> "My contest entries". There you can edit your entries and upload a hi res version !

well done, just wish they weren't hanging off the top, with so much space below. I haven't voted yet, but I suspect it's an author who had similar framing and no High res last week.

perfect

Thanks, Nator
