There are so many ways to draw a portrait but drawing an interesting one is not always easy. Here I decided to experiment with sketch portraits using various pencils and decided to color the background with a single marker. I just picked a color that seem to fit the portrait. I wonder if it's because of something you can pick up from their personality in the photos, kind of like an aura (not that I know much about that). So just for fun, I decided to check the colors out on some random color personality website, and what the chosen color said about my perception of them :
Portrait no 1 : compassionate, empathetic and caring.
Portrait no 2 : practical, down-to-earth person with a love of nature
Portrait no 3 : extroverted and optimistic, courageous and confident.
