First you need that lighting. A curtain is a great way to diffuse natural light. You can also use a reflector so that the face gets good lighting. Keep an eye on how the lighting changes to know what you are shooting. Take photos of what you want in the morning afternoon and in the night. Keep the lighting simple shoot with what you got. Shoot raw to fix what u want later. Light is the best in the middle of the day for contrast. Homemade lights make a comfortable lighting. Also fix your ISO and aperture.
