You can change it back to private in work if you must, but adding an acknowledgement to the original source should be fine. Your take is a bit different so does not need to be cast away into the darkness :) Go to Comment
For the Genre, this is a great in-depth exploration of the character - really a work of fiction that frames her. I like the tone of your world and your writing - it is very coherent and very consistent. Top quality work here.
