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.
Keep an eye on the weather outside. Weather conditions can create many opportunities to improve or destroy a great picture. You can still get some great outdoor shots on a cloudy day. Compose your photos so that the gray sky is not actually in the frame. Don't let it stop you from taking great pictures.
Take your pictures quickly. The longer you hesitate, the better the chance that your subject will move away, break their pose, or become tired and stop smiling. Start taking shots as quickly as you can, and don't worry about getting the camera perfect before the first shot. The faster you shoot and the more photos you take, the better your chances are of getting a good one.
