That's a great summary. Another telltale sign is the discontinuity in the partially obstructed background.
If you have a human subject in the foreground, the parts of the background to the left and to the right of the subject do not connect properly. What should be single continuous parts of a building, a window, a railing or a landscape are drawn on different heights or otherwise do not form a whole structure.
By consistency I was meaning to say wrong continuity as you put it.
BTW for some anime images I felt like i have seen them on that subreddit. Even if not those exact images, I have seen similar. That particular style (coloring, smoothness etc) also made me look carefully for flaws.
Those particular images were so generic with the characters lacking any distinct traits, they could have easily been from either Stable Diffusion, or some ultra-low budget visual novel.
- missing symmetry in faces, symmetry in clothes/costumes
- lines ending up nowhere. AI diffuses lines into something else often
- bad hands, bad eyes
- nonsensible scale e.g. a mountain shouldn't look that big or that small
- missing consistency. AI tends to loose consistency easily.
- badly written text, AI can not do text properly. if you can make sense of text its not by AI
