There's really no reason for anyone to be confident that this is or is not fair use. The law around fair use is a quagmire of conflicting ideas, cases, and opinions and most of the law is in the form of precedents since the letter of the law is so vague.

One only needs to read the Supreme Court decision in Andy Warhol Foundation for the Visual Arts, Inc. v. Goldsmith. In this case, it was found to not be fair use, but with a forceful dissent from Elena Kagan. And this is just a straight-up use of a photograph / art-piece. Add technology to the mix and things get really messy quickly.
