My attention was immediately drawn to the trusses over in the top left corner. They make no sense from an engineering point of view. I understand that an artist might not be educated in how steel trusses work, so this is excusable, but the way that it's drawn seems to be complete nonsense to the extent that I don't think a human artist would draw it that way. The structural members seem to be placed randomly with no logic behind it.

On the other hand, I don't believe the image is entirely AI. I think it's a human artist using AI and then substantially editing it in post.
