The light is nice and the shallow depth of field help separate the subject from background.
The light is smooth, and the beverage has a sweet golden color. The expression of the lady is really candide. I like that she is framed on the left, with room for the setting.
But she is maybe a little too cropped... Maybe if you had zoomed a little less.
Hey, in the background isn't it another shutterbug holding a point & shoot cam?
EDIT : What were your settings? (ISO, Aperture, Speed, lens used, focal selected)
