Portrait lighting with artificial lights

For this assignment, I took pictures of my mom using three different types of artificial light. I used two different lamps and a flashlight. I used 1250 ISO, florescent lighting as my white balance, and 3.2 for my aperture. I used +1/3 for my exposure. What I noticed while doing this assignment was that it matters where you set the light, so that you don't have a shadow on their face.
