I’m working on an icon of a framed painting. I would like the painting to be immediately recognizable to the intended audience, and so am considering doing a stylized reproduction of a particular painting from scratch to include in the icon. The original painting is copyrighted. Is there any legal problem with doing this?
Stylized or not, reproduction of copyrighted work is derivative and subject to the legal issues that brings. So short answer… No, it is NOT okay.
You would be better off using a painting already in the Public Domain.
