I don’t know if you know this but Peter Pan’s copyright is weird in the UK. There is a legislated exception in the law that it never expires and the royalties will forever go to a specific children hospital. Here are the actual words: https://www.legislation.gov.uk/ukpga/1988/48/part/VII/crossh...

(Now i don’t think you are necessarily in the UK. Just wanted to explain that Disney is not the only reason an AI might be trained to thread carefully around copyright issues of Peter Pan.)

You can also try asking Gemini to create art that is "as close as possible without infringing" - I've had success with that.
