She is pretty but the lighting is quite harsh.
Her right cheek and the right side of her neck looks almost burnt out while her left cheek is red. The dark of the sweater is almost completely clipped.
Her lips are really red - either lipstick or saturation - almost a cross-processed look. In either case, she looks a little young for the lip color.
While this is an interesting 'look', IMO this picture depends for its impact on the native prettiness of the subject and the unusual 'look' rather than anything else.
