The compositional rules for photography are the same as with any 2 dimensional art form. You might take a moment to look them up and see how it works for you. There's only so much you can learn from looking at other people's work though. Like most things in life, it comes down to the old Carnegie Hall joke.....practice, practice, practice.
There's probably more to be learned from studying the compositional rules for paintings, even though most of them are about using different colours. For instance, putting a person or other living being in your picture means the viewer will first focus on that, and then the rest of the work. We're configured this way by nature. We're also attracted to high contrast, and our eyes will go to the area of the photo that has the most of it, so don't place that in a corner of the photo. After you've done this a while and know what you're doing, then you can break the rules.
Wouldn't hurt to take a class or workshop (these things are fun!) w/ someone who knows their stuff. When I was starting out as a painter, I had a large nude painting in progress on my easel when my friend and mentor stopped by the studio. Before he even entered the space he saw the painting and said "Her feet are too small". And they were. Hands and feet are really hard to get right. Sure, sooner or later I would have figured that out, but his comment saved me from continually making the same mistake over and over until I did.
