How to draw clouds

In landscape painting the emphasis often falls not on the ground but on the sky. And the main characters in the sky are the clouds. When they work with clouds, beginner artists quite often forget that clouds have volume, lighting and an inner form of their own. And when it comes to difficulty of proportion, the only thing clouds lose out to is a crumpled piece of paper (which is also a super cool exercise for proportions). Anyway, enjoy the watch!
