Apart from camera settings, the best thing to help your photography is to know and understand composition. Start with the Rule of Thirds and work your way up from there. Basically, avoid the compulsion to put your subject in the middle of the picture; put it to the left of right of centre. Easy fix, you'll find most of your pictures improve straight away just by remembering the RoT. Another compositional guideline is to always have a point of interest in your photo - there should always be something for the viewer to look at. Just as bad as not having anything to look at is having too much to look at - but Depth of Field (AKA Aperture setting) can help here. My final tip is to always THINK before you press the shutter button. The difference between a photograph and a snapshot is only a couple of seconds, but stopping to think about composition, points of interest and so on is essential to good photography. I may be biased, but as a photography tutor, I'd highly recommend attending an adult learning class to help with your photography. I find it's easier to learn with somebody showing you than it is to learn from a book.
