Miss C. Photo shoot

It did not go as planned. Why? Oh because of the twit behind the camera that's why. All I can say, is that I need to really learn this "studio" work. Studio being inside, with limited lights. I borrowed friend's Canon Speedlite 580 strobe, so I could master it with my Speedlite 430. I had one reflector, but had no idea what to do with it. All in all I realized that I need to read up a little more before attempting such a feat. I managed to get 4 fairly good shots, but nothing that I was planning. Live and learn I guess. Thoughts?
