@Pixwix272 okay cool!
1) for the first one I downloaded a photo with a white background(on we heartit) and I used the app Vsco cam (using the highlight tint) for the pink background. I then saved it and user phonto to add my title and text
2) for the second cover I saved a piece of art on we heart it and I didn't apply any filter/highlight tint and used phonto for my title and text ✨ :)
