concentric Cube

A painting made on three square panels creating three faces of a cube. attempting to create what appears to be concentric rings, but only from one perspective.
light works in mysterious ways. some of the rings only look round from far away and some only look round from up close. I have to do some research on perspective and such I’m a little baffled by how it works and how to work on such a surface. I tried projecting. it was difficult to line up and I could’ focus it on the whole thing at once. I found another approach that worked better for me.
