While you look spectacular, you could use some pointers on lighting to make for even better images. First of all, placing the lights below the subject (like the one to the bottom right here) puts weird shadows across the face (like the one from your nose going up toward your right eye) and the chest (from the shirt that goes over your shoulder. Try to keep all lights at least 20 degrees from above you, this will look more natural and create more appealing shadows, if you want to "lighten" the shadows under the chin (that come from having lights above), use a reflector or a white big sheet of paper/carton. You are doing one thing quite right though and that is to keep one light (usually called the key light) stronger than the others (to create depth/definition).
- lighting takes some time to master, but with some fundamentals you can make a lot of improvements. It is so much fun when you really start to get the hang of it. You have what is most important already, a great model and knowledge of the camera.
