I'm very new to Adobe Stock. So I would like to know more about...
1) if the drawing that I upload to Adobe Stock is the drawing of my own Original Character / OC , am I still have the full ownership / license in that character ?
2) same question as number 1) but change from "Original Character" into "Original Story" (like, an illustration or comic page)
3) can I upload Fan Art in Adobe Stock (for example, if I draw Geralt from The Witcher, or Spiderman, can I upload here?)
Sorry for my bad English, and thank you for reading and answers
You continue to have all rights to works uploaded to Adobe Stock, provided they are your origninal creattion, and not that of another. Pleease refer to https://helpx.adobe.com/stock/contributor/help/submission-guidelines.html and all the links therein.
Fan art is by definition using someone else's intellectual property. You would need an intellectual property release. The owner is unlikely to agree to you making money from it, but you can try.
I am not sure this is the sort of thing Adobe Stock is looking for, but you can try.
