Hello. You want an original handmade drawing without AI or stock images, did I understand correctly?

I think hand drawn or a mix btw the two. Whatever looks the best.

Not all AI images and stock images can be used for tattoos. Then you should specify that you allow the use of AI and stock, otherwise the "designer" who won with the AI ??image will be subject to a number of complaints and will be deprived of a license or excluded from the site. By default, AI cannot be used in this (tattoo) section, and for stock images, artist should purchase permission to use, if there is no such permission, then this is also not welcomed.

Got it! Thank you for the clarity :)
