are the edits made from ur artworks, or from google?
i mean, if its ur own work that has been edited(filters, and stuff ya know) , you can still claim it as your own.
hmm, you can try to see if you can get the og artists Permision , like be on twitter or insta (im on twiter),
and try to do research lol
oh and to post edits, maybe use youtube or deviantart? idk-
if its undertale/delatarune related u can surely post it in undertale stream (obvi)
