I always love to leave space in my images. I often call it “the way the image breath”. When I do portfolio reviews I often see photographers really zooming in on the model like they are afraid that they loose megapixels they paid for.
If you leave some room you will see that an image is way more pleasant to look at and also draws the viewer in more.
On location this becomes even more important. Show that location. Don’t just shoot a model against an old wall (that can be anywhere) but really show the location you were in.
