Steve just keep these things in mind when you're shooting and you'll get better. Ultimately there are three things that make for good photos. The first is composition, this is simply the placing of elements withing the frame. What is an element? Well it can be anything in the frame, it's not always just a head or a rock. When taking pictures try to break everything in the frame down into shapes and tones. If you see a big bright spot in your frame, say from the sun, ask yourself how you'll balance that out with other elements in the frame. A lot of times it's as simple as placing the big bright spot opposite of another bigger bright spot, say something like a well lit face. At other times getting rid of it by simply moving is preferable. The second thing to keep in mind is the type and quality of light. Most people know it when they see it, but many people ignore it when taking pictures. Train yourself to pay attention to the light in your frame. Ask yourself, where is the light coming from, what's being illuminated by it, those types of things. Soft, even light is often prefered over hard light but this is not an absolute. As a tip, our eyes are naturally drawn to lighter areas first, so if your daughters back is a big bright spot and her face is hidden by shadow the first place most people will look to is her back. Finally the third and most powerful thing that makes for a good picture is the moment or story, sadly this is also the most difficult aspect to capture. We all know great moments when we see them but capturing them can be something far more challenging. If you can train yourself to be aware and anticipate a moment though, you'll be doing alright.
Keep at it, photography is a life long learning process.
