Whole books are filled with tips on photography, so it's difficult to be concise. I find the best results come from thinking carefully about what you are seeing in the view-finder. Think about what it will look like when printed and try to frame it before you take it. Make sure the sun is towards the back of you to get the best lighting, and if you really want a good shot of a scene, don't be afraid to take lots of shots in order, hopefully, to get at least one good one. The main thing, I think, is to experiment and keep practising.
