Today for our Rule of Thirds practice let's divide our image horizontally; placing the subject on either the upper or lower third instead of left or right. Using a horizontal placement can be visually appealing when the majority of the subject fills the frame as it does with a landscape, or architecture, or when the horizon is included. By placing the top of the sand dunes on the upper third it becomes the main subject instead of the sky. 

Choose a subject that you can make appear continuous through your image!
