Can't see the person for the tree

If you have any time to think about it at all, look at what is behind your subject. Do they have a tree growing out of their head? Or some other kind of distraction? If so then maybe you could shift yourself or them to fix the problem. You want to have your backgrounds compliment your subject and not distract from them.

Today's assignment: Grab your camera and pick to objects - you don't need a real person. Put your self and the two object all in a line. Now look though the view finder (or the screen) and then try moving around a bit to the left, a bit to the right. The objective is to get a feel for how much movement it takes to make a better compostion.

Advanced user assignment: Do the same as above, but also try to use the rule of thirds.
