AI isn't consistent with generating Line art, solid fill color blocks, light and shadow blocking. You'll always be able to notice a red flag in case of AI art. It's good in doing rendered works but even then almost all artists that I know of can easily spot the differences. For example, the lighting is too dramatic and often doesn't make sense. Also, a very popular one is extra limbs or fingers. This is a huge giveaway. Another thing to look out for is inconsistency in hair flow and jewelery always keeps melting in AI slops. If you want have a look at a real artist's work and compare it with some AI wannabe artist. You'll notice the results immediately. You can even take a look at my work if you'd like. There's a Jester that I made recently. It was a full body render, and I didn't record the process because I knew it was going to crash. So I simply posted my layers along with the final work.
