Some shots like this really work -- some don't. This one really works. Sometimes I just have to stare at the image and absorb it to tell what it is that makes it work.
I think lots of things work with this image. The styling -- the selection of clothes and accessories -- works. I don't have anything that "interrupts" the image.
I like the lighting, it brings us into the image but provides a little shadow on her face that keeps her "mysterious."
The crop keeps everything in balance -- but offers us an inviting look at her hands, her pearls, her clevage.
One of the great challenges is to be able to put this image together BEFORE you shoot it, rather than picking it out of the edit AFTER you shot it.
Can you tell us if this was planned or captured???
