Welp, first time using this kind of thing, but i noticed that sweeetdonnut style is way too similar to ebora's. So i check their pixiv for more images, and in a few there are signs of Ai.

Once again, on the third piece, if you check the left leg of the man, you will see that his muscle is drawn like a piece of cloth, as is it was a fold of the shorts.

Over all, bad anatomy, the man's hand are weird, and the back of the girl is way too off.

Fingers yet again.
And you can continue to notice a lot of errors on the rest of them, none of their posts are tagged as ai-generated on pixiv. Maybe i am just seeing things, or Ebora made a new account... and disabled the comments on a few of them, for some reason.
