Make sure you have a focal point for your photograph. This should be the first thing that the viewer's eye is drawn to. Whether it's a flower, a person, or a bird, every shot you take should have a specific focal point. Don't only think about what the focal point is, but figure out the best spot for it in the shot.
When you are planning to take an action shot in advance, get educated about the subject matter. You cannot take a good shot of something that is moving if you don't understand the types of movement involved. Learn about the movements of the subject matter and it will show in your photos.
A good photography tip that can help you is to take a step back from your work sometimes. A picture you might not have like before might suddenly seem appealing to you. It's very important to step back from your work so that you can always have a fresh perspective.
