Would you say this is fair use or copyright infringement?

Copyright law has a lot a room for interpretation. That’s what makes it so complex.

Some of the answers here bring up Derivative Work. This means that you used major copyright-protected elements of the work. However, if you use enough of your own personality in the piece then it may be considered an original. Of course, this can all be subjective.

Does your work qualify as a copyright infringement? It’s hard to say.

You should consult with a copyright attorney to know for sure. Check out LawTrades. We can connect you with a qualified attorney that can help you more with this.
