A Strobist in the Making - Studio Photography

I just got my muslin backdrop, a reflector and a 580EXII flash. I didn't want to have too much hassle in the setup of studio lights, so I tried using two flashes: the 580EXII as master and my old 420EX as a slave. Here are the test shots from the upcoming strobist :-) The models will not complain if the shots turn out bad. I'm satisfied with this initial attempt for studio portraits, though there still are improvements to be made.
