Incorporate things like roads, streams, shorelines, railway lines, or even railings, into your images. These are referred to as lead lines and are a great way to capture the way that a viewer is going to look at your photo. They will lead your viewer's eyes through the scenes of your photos.
A great photography tip is to make sure your shots have depth in them. An easy way to achieve that is to be sure that you have a background, a middle ground, and a foreground. Having all three of these will give your pictures a sense of atmospheric perspective.
