First Studio Headshots

You've got a second light low and camera right that is throwing conflicting shadows to your main light. That's giving you ugly shadows across the right side of her face.

Maybe you meant that light for fill or to broaden the effect of the main light.

To broaden the main light, you'd need to put both of the individual lights behind a common sheet of diffusion material.

If your intent was to fill in the shadows, an active (actual light) fill l should most safely be at the camera position. It can be right over the camera so that any shadows it throws fall out of sight behind the subject. If youi're using a passive fill (reflector), that can be to the opposite side of the main light so that it can catch light from the main light and throw it to the subject. By it's nature, a reflector won't be quite as bright as the main light.

For butterfly lighting (main light over the camera), it can be just below the camera.

Either way, it must not be so bright that it deforms the shadows cast by the main light.
