The sight of the sky and the clouds that populate it is always suggestive, and can create the most varied emotions in the observer: a clear sky can calm and cheer up; dark, clear and ready to unleash the storm, it can inspire fear but also admiration and beauty; if it is of a particular color it creates curiosity, expectations and estrangement.
Images of this kind are excellent for making emotional or closing scenes, or for moments of reflection and full of thoughts; lends itself well as a background for captions or to take your eyes off other scenes.
