What are you into? What do you mean by compositions? A decent photographer should be interested in all aspects of photography and be good at it. But this is just my humble opinion. If I say anymore I'll get in trouble.
Compositions trying to put an object in a different angle to get a different view... (quick explanation). I'm more into landscapes and catching things you only see once...
Anyway whatever you can think I'm not a decent photographer I really don't care about one man's opinion
