I like these they look great,...you asked
The top one where you used two lights in frount, the light on subjects left should be higher (notice the position of your lights in their eyes), See the shadow of her nose, bounceing the main light with a white card back into the subject is always a garantee of a soft fill and a good replacement for the secound light.
the bottom photo with the one mainlight is higher and flatters subject. I like the rim light you got from putting your secound light behind.
sorry if thats to much info ,I can't help myself sometimes.
this is cool.
