2 light setup photofloods + on camera pop up flash

Comments- suggestions?

I am actually a bit confused why there is graininess. You say you shot at 160 ISO so there should not be any there. I am not sure if the graininess was an effect that you were looking for. If not I would check to see if your lenses are as clean as they can be. You should center your subjects a bit-more she is leaning in too much the pose does not seem natural also she is really squinty. A photographer once told me i"f you have their eyes you have the subject." Make sure you can see their eyes and see them well. Also lighting on their eyes it all does no good if you cant see them. I am not sure what flash you used but it looks like a mounted flash based on the reflection on the back drop. If you can't defuse the light better you should consider shooting outside where natural lighting may add some interest. Provided of course that the weather is good. I do not proclaim that I am an export I some times reply so that I can think through things I might do to make it better. I am in a constant state of learning. Happy Shooting. Oh haha I was also going to ask you what lens you were using.
