Avoid merging: Mergers are created when key parts of the main subjects overlap each other, touch another key element, or touch the sides of the frame. (Example: a tree growing out of someone's head)
Avoid center weighting: center weighting is when you do not follow the rule of thirds and the subject is in the middle of the frame.
