@serenapowell5 Yep I designed the cover, so basically when it come to making a cover I looked up some photos of Jungkook as a wallpaper and put it into my editing app (you can find some nice free ones that works, I used Pixlr and Lumii as my editing apps) and you tinker with the lighting, whether you want it to be in black n white or other sort of shade. Then you put your title in whatever text you want and your name.
Or, if you want something simpler, you can actually just look up aesthetic wallpaper of whoever you want to write about, if it's a fanfic. But if it's an original piece, you can look up aesthetic wallpaper that matches the plot of the story.
Sorry this is extremely long, but I hope this sort of helped
