Copywright in watchface images

can I use images from Music Bands in my watchface creations? I recently created a watchface with an Iron Maiden ilustration, shell I delete it? is it OK?

Hi and Welcome,
As long a you have permission from the owner of the copyright, it will be fine. Don’t forget to give attribution. That is also true for any images that you use from free image sites such as Adobe Stock, FreePik, etc… Otherwise it is a violation of their terms to use one of their elements as a main image on a published watch face.
Maybe you could keep it in your drafts and just use it for yourself without making it public.
