Grace108x inhabiting the booty chair (Patreon)

This is backlit from my two studio windows. Backlight is by far one of the most accessible and most stable lighting scenarios possible:

Place the model approximately at 90 degrees and to the window/or light source. Ensure the light mostly shines in front of the model so there is a larger feather around the shadow side instead of the light source pointing directly toward the model.

Subtle differences between these, do you have a favorite - and why?
