Well, I hope you did not promise them anything to them. The photos are "amateur snapshots" and I understand your posting them here to get some reaction. You could have done more to pose the models, clean up a shooting area, perhaps bounce the flash and use a reflector to give some 3D lighting. Simple stuff that anyone could do even on a ad-hock test shoot.
The first girl "might" work for you if you really dress her up, makeup, hair and really work out a nice set and lights. I don't think you can do anything with the second girl.
