This uses almost the same pose as my "Behind the Scenes" image with the expression, hands and feet changed slightly. If anyone has spent any time on Pintrest searching "Supergirl," you will know where the inspiration for this comes from.

Lit with a sphere to camera left and another to camera right one stop underexposed. The background is a rendered image of Earth with the black levels increased and a gradient placed on the top layer. I then used Color FX Pro to give a slight color tone to the overall image.
