You have read me say this over and over. I cannot say it enough. Amateurs look at an image from side to side - laterally. Pros that shoot landscape images look front to back - into the image. Pros do everything they can to draw the viewer into the image. They try to create depth. When a viewer looks at your image from side to side they see a flat picture. When a viewer looks into the image; front to back they are not looking at a picture but looking at the scene as if they were there on location looking at it.

Look at this image. Did you look at it from side to side or did your eyes move into the scene from front to back? We draw the viewer into our images by using lines, balance, composition, light, strong anchors (foreground, middle-ground, background), and such. Firstly, we attempt to create depth by composition. This image starts with a strong foreground (cactus). It has a strong middle-ground in the water, and the peaks make for a strong background.

          We also use post processing to enhance the depth because we want to draw the viewer into the image. I lightened that cactus quite a bit to make the viewer start there (our eyes go to brighter parts first). The edge of the "pool" forms natural lines that lead into the image. Although this edge was lighter than the rest of the rock, I lightened it even more and darkened the surrounding rock to make the line more pronounced.

          The goal with such an image is to draw the viewer into the image. Now not all images has a strong foreground (and not all images need one). But you have to pull the viewer in. Use light, use focus, whatever, but invite the viewer into the scene instead of leaving them to watch a flat print / screen.

Once again, I made the lines that go into the image more pronounces (darkened the dark and lightened the light). Go ahead, invite your viewers in, draw them in.
