Respect the Pouch.

For these, I tried using a blockier shape. Not 100% blocky like a rocky texture but slightly bulkier. I made the shapes feel cloudier by adding subtle textures near the bottom half of the cloud. I noticed that if there's too much texturing near the top, it ruins the flow of the entire cloud. It feels unnatural for some reason.
So ill keep this technique in mind for future clouds :D
