me and my waifu are analytic art viewers who dabble in the craft from time to time.
When I opened this image initially, I brought her over to review it as there was a perception problem that was reaching out to me, however I personally have eye damage, so I thought perhaps it was my eyes creating the perception flaw. Using her young and healthly eyes, we confirmed that it wasn't viewer based but art piece set.
We examined this picture further, and found multiple things that bothered us on an artistic and analytical level, that ultimately to the untrained eye would go unseen due to the quality of 51%+ of the shading/colorization, and the intended audience.
It actually fascinated us, the more we analyzed, the more we found incorrect. It's truly a curious piece.
