I'd like to also add that it can help if you find a few people online that shoot the kind of subject(s) that you intend to shoot, and then take a close look at their work. See if you can work out what it is about their good photos that make them good.
For example, with landscape photography, is it the subject that's interesting? Is it the way they've framed it, with recognisable foreground, mid ground, and background elements? It is the balance of in-focus and out-of focus elements? Is it simply the colours and textures? Or the way they break 'the rules'?
All of these factors can make an OK photo idea into a good photo if executed well. And they apply to almost all types of photography.
Also, find some famous photographers and look at their work, to see how it differs from yours. You might not get far in trying to emulate their technique this early, but keep it in mind as you progress. You'll find that you start to develop your own 'voice'. Then, frustratingly, you'll probably lose it and find it a few times along the way. Don't take it all too seriously and you'll have a lot of fun.
