I heard for belly dance one needs both muscular stomach and fat which can be jiggled appropriately. Despite this belly dancers tend to be fit in my (not a lot) experience, enjoy showing off their abs.
Which brings us to our first thought about her. Performers do their stuff to entertain others and/or hand over an impression, emotion, information. While they are doing this they get feedback from the audience, good and bad but they mostly looking for the good. They not just doing it so the audience feel good or become richer with the experience but to make themselves feel good about themselves. They tend to measure their own worth by the reaction of the audience. This is especially true when the art is the performer his- or herself, their shape and movement.
So first I would say she is proud.
But in her business to gain positive reaction she needs to put work in it. To keep her fit and practice her moves. That's can be achieved by determination and diligence.
Her smile looks unnatural tho.
