Thank you! I haven't made one in a while, but when I first started out, I used to Google Jisoo with key words that fit the mood of the story I was planning such as "cute" or "dark," but after she made an IG, I go looking for pictures there. I also look through fansite and photoshoot images to find some. For a book, I would put the image in the Wattpad book cover app to make sure it fits on the cover.
