You will be taking a lot of portraits for this assignment. The idea is to learn through practicing. The more pictures you take, the more you will start to feel confident creating portraits, choosing backgrounds, using lights, using props, directing models, and choosing the best camera settings.
Put your research to work at this stage. Apply the hints and tips that you read about. Experiment, be creative, and have fun.
Each of your 6 shots should be different. Try changing the zoom amount, shoulder angle, head tilt, looking at the camera or away, smiling or serious, intensity of lights, background, sitting or standing, on the floor, with and without hands, etc.
