Hey, sorry for the late response, but the backgrounds don't come with the set.
Though, if you want to make the cloudy sky then I recommend checking out my last asset: https://kassjak.itch.io/20-clouds-pack
Cheers!
Oh very nice! Thank you for providing the link. I like how you use to same clouds to create a very nice background in this link https://img.itch.zone/aW1hZ2UvNTQwODQ5LzI4MTU3NjIucG5n/original/e28cvo.png
