Do not stop taking outdoor shots when the sun begins to set. There are many opportunities to keep going, especially if you have a tripod available to use with your camera. This piece of equipment allows for great low-light shots no matter if the sun is up or not.
Incorporate things like roads, streams, shorelines, railway lines, or even railings, into your images. These are referred to as lead lines and are a great way to capture the way that a viewer is going to look at your photo. They will lead your viewer's eyes through the scenes of your photos.
When working around subjects that are moving a lot or are totally in action, you need to focus on capturing the moments by keeping your trigger down. These kinds of moments can not be recreated and there are no do-overs. Keep your eye on the areas at all times and keep shooting.
