Thank you for sharing your work. I like her very natural expression and the way she looks over her left shoulder...
Her eyes and facial features seem to be a little out of focus, though... or she may have moved? (as the picture on the wall seems sharp enough and certain parts of her blouse seems sharp)
You've captured Mandy's expression at her best. Unfortunately, the OOF and distracting background spoilt the photo. If not, this will be a great photo. Shoot more, and I'm sure you'll have superb photos to show us the next time round.
