If you want to be a good photographer, concentrate on taking good pictures and leave the cutesy stuff for others. Don't get caught up in the ability to do cutesy. And this is not bokeh - bokeh is the way the lens handles out of focus points of light.
This is not a particularly flattering picture of an attractive woman, the light is relatively harsh and she has shadows under her eyes and her chin.
She is crushed against the right margin while completely meaningless background lights take up 2/3 of the picture.
When there is a relatively dark situation and your subject is wearing a dark shirt, her head will appear out of nowhere
