I think no one can tell you because I don't think the courts have
defined "fair use" with any precision.
People who want to be safe get permission, but of course that's often
impossible. Many artists just go ahead without permission. If the rights
holders aren't very litigious, and you earn little money from your work,
you could be pretty safe.
I'll be glad if someone can correct me.
