I like the style, and your choice of model - but do find the shadows across her face distracting. also not to sure about the leg position - or perhaps its the lack of shadow detail that bothers me.
I think you could have cropped to the top of the sofa and eliminated the visual clutter of the drapes. Need more detail in the pants. Very nice and crisp focus on the model. You've made her complexion smooth and lovely. Maybe a little greenish to the tint?
