Do writers also count as artists in gcse photography

Helloo 👋 I’m basically now planning for my big piece for my photography gcse exam and my theme was other worlds, I chose multiple artists, have done a lot of research pages but I wanted to base one of my ideas on a book (the cruel prince) I chose fantasy subtheme to fit my work and that’s why I wanted to base it off that but since it’s a book it does not really have any pictures so I chose an insta digital artist who drew how they invisioned one of the characters looking like digitally, can I base a shoot of that and basically do digital work, will that count? And in my book I wrote about both the writer and the insta artist and how they inspired me to recreate (I don’t know how to word it)

Yes! Writers are a source of artist research as they also connote creativity.

Alright thank you but I don’t know how to add them to my photography book, I don’t know how to say this but like how would I do shoot plans or do I do shoot plans based of scenes on the book and how I believe they look like?

You could use scenery and try to find locations or perhaps collage objects within your surroundings and interpret it based on the book's scenes.
