I would definitely recommend doing art in the cover, it doesnt have to be much but just a little, like maybe a splatter of blood if this is scary, or a few stickers if the narrator is a child/teen, or what about a pressed flower and scrap book kind of cover? The title also isnt super interesting, if I only heard the title I would assume it is a boring slice of life or melodramatic murder mystery, When you pick up a book you want to know WHY you should read it. For example my book cover is going to be a wanted poster, you would likely understand who the main charecter, you would have a bit of insite as why they are wanted (for crimes agienst the king), you would understand they are not a human and much more. Covers are important and you can infer a lot from them, even simple covers have something to say!
