After reviewing the first test shot I noticed the light on Rob was a bit hot and Stacy was a bit dark. With using one light, I needed to feather it a bit more to get an even exposure on both of them. So I brought it from 45 degrees around front a bit more and aimed it at Stacy. I was also loosing Stacy to the back ground with her black coat.
So I went inside and placed my second light on a mini foot stand and aimed it up at the wall to give some separation and depth to the photo.
You'll notice that my exposure settings were the same in the 2 photos above. By bringing the front light around a bit, I was able to even out the lighting on both subjects.
And here is the final image.
