Desert Background

This is a base for a desert background I'm working on drawing - https://i.imgur.com/Z7HTgAt.png

The waves in the foreground are sand hills and the triangles with lines drawn at the center of them are pyramids. I plan to add some more detail to the pyramids and maybe add little cactuses to the sand. As for the sky details, I'm thinking of making wind patterns as well as have a more scorching sun as deserts are typically hot. The sun really needs to convey that heat factor.
