Rule of Thirds
 I followed the rule well. Except there was distraction in the back with an another in individual in the hallway. 

The subject is the the young lady facing with her back towards the camera. She has short black hair with streaks of green. 

She is fully in focus and the viewer can clearly see she is the subject.

I believe I accomplished this rule well I would only take away the person in the back to have the focus mainly on the subject.
