Take successive photos of your subject if there is a chance that it might move. Certain subjects, such as wild animals, won't just wait patiently for you to take your photo. In this case, take one shot quickly so that you have something to work with. Then, if the subject hasn't moved, take more shots with better positioning and composition.
To avoid red eyes in your photographs, make sure that your camera either has built in red eye reduction or you change the direction of your flash. If you did shoot a photo and it contains red eyes, you can easily remove them through the use of a graphics software such as Corel or Photoshop.
A great photography tip you should keep in mind is to never compare yourself to someone else. If you're constantly comparing your work to someone else's, you're selling your own work short. You must learn to value and appreciate your own work, and not worry too much about everyone else.
