Frame that girl
Framing can be very important in a pictures, especially for a photoshoot like this. When you can from a subject you can make them stand out a little more than just a couple of head shots. when the model is the center of the attention but there is other stuff going on it makes that model pop even more out of the picture.
Framing also adds layer where you can make it less like a flat picture in some cases and stand out more like a 3D photo because you know that the subject and whatever object is not next to each other
