I agree with bluefrog. The outside shots look fine as far as using the gold reflector goes. Nice skin tones. If you want to take it down a notch you can always decrease the REDs using color balance in PS.
On the last one I would have had her arch her back a bit more and form a curve that way. Also bring her head up some more. I think that might give the image some more power [img]/ubbthreads/images/graemlins/cool.gif[/img]
In the second to last one I would have pointed the knee and fingertips away from the camera. That might make the shot work a bit better.
Hope that helps.
