Hi Izzie, I'm glad I got you working your lights! It's fun, isn't it? It looks like you did a great job of softening and minimizing your shadows. In answer to your question: if you want to control the color of your background, yes, you will have to move your subject away from it. I can only refer you back to Terry's post, #33 above. Same goes if you just want to throw the background out of focus, depending on your lens and aperture: advance your subject away from the background.
Not to complicate things, but to file away for future reference: A neat trick for making a background gradient is to slope the paper or cloth your subject is sitting on up and away from the subject at the rear. Potters often do this, apparently, when photographing their work. If you are only lighting your subject (not the background), the light on the background will fall off smoothly from the bottom of the frame to the top.
Your bears are sweet, but I think the brown nose bear has a few too many catchlights in his eyes in the B&W; makes him look a little crazed, don't you think? But who am I to say; maybe that is an accurate portrait.![]()
