While logic would dictate that it'd probably be better to have some kind of heavenly drone or something to go with it, I think that's a bit too obvious, and I wanted to create a little story to go with the clouds in the desert. It may be a bit too busy and in your face but I'm sure if you have any audio editing software you could edit a bit to go with it better. Hope you like.
