Upcoming fanfic (Cover)

The original title was supossed to be Fifty shades of darkness but then I rembembered about... that book. I changed the title of the fanfic for Shades of darkness and this will be the cover for it.
I know I am writing another fanfic already but this month I will have a lot of free time (except this week because of LOTS of colege work), so I will be writing 2 fanfics and giving more priority to this one.
So, I don't wanna give much spoilers, the story happens during Scar's reign, days after Mufasa's death, the main characters are Scar and Nala, but especially Nala because the story is basically her life since cub to young adult, besides her and Scar many other characters will appear especially OC's, and the main plot is about her relation with the mad and evil king Scar (Don't worry about the title, the story has nothing too ''heavy'' in it)

Also, since the story is more about Nala, do you guys think I should write it in first person with her narrating? Give some opinions if you want to
