Studio shot...

How do U rate my light set up.

What to change?

Im not a studio enthusiast...

I'm not a lighting expert by any means and shoot by available light whenever I can. In looking at your photo, though, I wonder if you meant to have the left side of her head and the hand in back in shadow. The shadow under her chin might be a little heavy, too, and her eyes are probably lit a little too harshly (the micro lines around them are showing too much - much like a shot in the noonday sun.)

The light on her chest is soft and well done.  I find myself zooming in on the chest when I look at the photo, which might be expected, but the good lighting there probably helps draw me in.
