Composition-wise, this is a well-balanced image.  The dark background separates the subject and brings it forward in the scene, making her the focal point.  The blue outfit casually complements the grays and the browns.  There is red fruit, chairs framing the subject leading your eyes to her red hair and tattoos.  Very subtle but you can't help notice it.  I love the yellow cups, it's that sudden splash of color that captures you.
