I'd agree with. If the black slacks were a good fitting pair of jeans it might also help the over all image. The slacks bulging the way they do is distracting. I also suggest denim as this model is young looking and the wardrobe suggests the opposite.
I agree that the wardrobe has an impact on the overall image. The Dark navy and the orchid magenta does not work well with window lighting. It does not correspond with the models expression. Then again it might be just the back ground theme.
