High Key portrait shots

I am still learning how to set up lights for different kinds of shots. Today, I was aiming for simple high key lighting. I think I still have a long way to go, but I would appreciate your feedback. We were limited in terms of spacial lay out as our family room is reasonably crampt.

My own criticism:
1. Our monitor is uncalibrated so the WB may be off, and the shots could do with some more contrast, I reckon.
2. If I could, I would place the main background light further away from the camera angle.
I would appreciate yours.
