I've got a degree in Creative Arts, Photography (quite long time ago tho lol)
I have struggled as well writing an essay.
but from my experience, you will be asked to name some photographers/artists
you have researched to back up your project.
What tutor wants to know is what you study through your works not just if your works look good. so it doesnt need to be just a photographer, you can say you have studied "light" 'Contract' "why use colour" etc.
I can say much cos I havent seen your works but from your discription, you can even study David Lynch films. Good luck!
