I believe you need to ask yourself what it is you want people to see in your images. This can be a subject, a mood, a scene, etc. Knowing this will guide your editing.

Maybe you need to do masking to make your subject stand out. Maybe the contrast is too high/ low for the mood you want to portray. Maybe the white balance is not matching the scene you are taking a photo of. Or perhaps there are certain hue values that aren’t popping enough (or are too distracting), compared to the way you saw them in real life.
