I would also link this if you will: https://www.europol.europa.eu/crime-areas-and-statistics/crime-areas/child-sexual-exploitation
quote:
Child sexual exploitation refers to the sexual abuse of a person below the age of 18, as well as to the production of images of such abuse and the sharing of those images online.
This one: https://www.europarl.europa.eu/RegData/etudes/STUD/2020/652718/IPOL_STU(2020)652718_EN.pdf
says the same applies to drawings and AI generated images.
That's up to the interpretation if individual country courts, but I would be wary nonetheless about pictures showing people that could look like teens.
Edit: downvote all you want, laws are laws, if you like to risk it, good for you, I don't.
