nobody is saying anything because it seems quite obvious. But if you actually want an analysis I will write out my thoughts.

I have seen quite a few of both low definition game models and low quality pictures. This is not what a low quality picture looks like there's just too much wrong with it. But I immediately recognize the gallows as a low-resolution 3d model. Look at it's construction around the legs. There's also a lighting mistake here. kind of looks like playdough. But what if it's just low-quality picture?

I normally expect to see things closer to the camera have more detail than the things behind it. This doesn't. Look at the horse and things way closer. Look at the cinderblock wall. and then look at things closer still. It doesn't pass.

Also the lighting on the entire asset of the gallows doesn't match with the lighting of everything around it.

And if it's a picture of a 3d game asset as I said it looks to be. Then you would have those optical illusions. A better question, why is it we can tell that it's a cinderblock wall but can't see the lines, shadows, or construction of anything around it.

Further more feel free to look up on google street the Andrew Jackson horse statue and notice that the angle of the picture shows the structure to be impossibly placed.

There is nothing about this picture that feels legitimate.

Also there's a content aware fill behind the selectively textured 3d asset. That's why you see a slight faded repeat in the background.(2 pathways)
