Jessica is a attractive model and that dress shows her off well.
A couple of points. I find the background distracting, because a) The pattern, and b) Jessica is standing too close to it.
If you have got the room to do so, have your model about 3 -4ft away from the background so that it can be placed out of focus.
The lighting of the face, may not be to evertyboby's taste, you might want to experiment with a) the placement of the lights (in relation to the model) and b)your light ratios.
