You were obviously near a source of electrical power, so use a clamp on light on your light stand with a 100 watt light bulb in it, or if your light source was an a/c powered studio strobe leave the modeling light in the "on"position. If you shoot in Raw and shoot a gray card you don't need to worry about the bulb affecting the white balance because it will be included in the gray card reading.
Critique. Image 1. The light source is rather hard. I would soften it up and then add a silver reflector to the opposite side to lighten up those dark shadows. Her right hand looks deformed.
# 2. Her hands are "spaghetti hands" and look bad. They are also have the brightest skin in the image. With her leg up it allows the viewer an eyeful of her crotch! Lowering that leg will prevent that.
# 3. Fists look great on prize fighters, football players and wrestlers, but not on beautiful young women. The female should have open flowing graceful hands. Her bright knees fight our eyes for attention and draw them away from her face, therefore the impact of the image is lost. Black slackswould have taken care of that rather easily.
