I have a suggestion you may want to try, to get rid of the wrinkiles in the backdrop, use the magnetic laso and draw around the girls, then invert your selection and apply a len blur to the backdrop, keep playing around with the lens blur settings unitill you find something you like
You may also want to duplicate the layer before you start, incase you get some blur on the models, then you can erase the parts you have to on the top layer.
Just a trick I thought you may want to know.
Its a good pose on all three girls I love the fun this photo projects, but you may need to use a reflector to feel in the girl face layer face down to the floor.
